Quantum Dot Solids and Their Application in Solar CellsDoping quantum dots (QDs) is a problem that has been haunting researchers in the QD research community for years, even though doping techniques have been utilized for decades in conventional semiconductors. For the “self-purification” in colloidal QDs, engineering the surface ligands has emerged as an effective way to alter free carrier concentrations and doping types in colloidal QD solids. Halide-atomic ligands are the most popular ligands in producing PbS QD solids since they provide minimal dot-to-dot distance while maintain low in-gap trap states. However, previously reported halide surface treatment could only produce n-type QD solids. Here, we report the fabrication of p-type PbS QD solids using proton-assisted surface ligand exchange. We unveiled the origin of p-type doing in PbS QD solids, and it came from an unusual surface ligand; the HOH+ group formed using NH4X (X = Cl, Br, I) in methanol. We further fabricated QD solar cells using PbS–NH4Cl, a p-type QD solid predicted and proved by our theory and experiments. The champion device shows a high power conversion efficiency of 7.49%.T12-P02, T12-P04 University of Alberta | Publication | 2020-11-01 | | Electrochemically reconstructed perovskite with cooperative catalytic sites for CO 2-to-formate conversionPerovskites are the promising catalysts for various reactions, yet their structure evolutions and the composition-function relation in the carbon dioxide reduction reaction (CO2RR) are not fully explored. In this study, we report that the reconstructed BaBiO3 (BBO) perovskite is able to facilitate CO2-to-formate (FA) conversion by both A- (Ba) and B- (Bi) site elements through the cooperative but distinct catalytic mechanisms. Specifically, the electrochemical reductions of BBO trigger the complete rearrangement of atoms with rapid kinetics at catalytically relevant voltages, giving rise to electricity-induced Bi metallene (eBBO) that efficiently generates FA with high selectivity and partial current densities. Moreover, the reconstructed BBO simultaneously enables Ba2+ release to the electrolyte, and the time-resolved FTIR and in situ Raman analysis collectively reveal that the Ba2+ adsorption enables easier CO2 adsorption, thereby leading to enhanced CO2-to-FA conversion. This work is of direct significance in elucidating the cooperative catalysis between A- and B- site elements in perovskites for room-temperature CO2RR.T02-P03, T12-P02 University of Alberta | Publication | 2022-06-01 | Mengnan Zhu, Bo-Wen Zhang, Minrui Gao, Pengfei Sui, Chenyu Xu, Lu Gong, Zeng, H., Shankar, K., Bergens, S., Luo, J. | Electrochemically Dismantled Perovskite with Cooperative Catalysis for CO 2-to-Formate ConversionElectrochemical reduction of carbon dioxide (CO2RR) driven by sustainable energy resources holds great promise for realizing the zero net emission of CO2 by converting them to value-added fuels.1–4 For the past few years, substantial efforts have been devoted to boosting CO2RR using different nanostructured catalysts. However, the complicated synthesis procedures and low product yields are usually associated with many of these catalysts, which hinder their scalability. More importantly, many catalysts suffer from the low catalytic activities, high overpotentials, and unsatisfactory selectivity, which collectively impede the large-scale applications of CO2RR technique. In this study, we pursue initiating the CO2 conversion on perovskite-based catalysts BaBiO3 (BBO) to selectively produce formate (FA). The structural/phase evolution of BBO under cathodic potentials, the catalytic performances of electrochemical and photoelectrochemical reduction of CO2RR, and the effect of non-active A-site element (Ba) will be investigated in detail.
Herein, BBO perovskite is fabricated by annealing the sol-gel Ba2+/Bi3+ nitrate mixture at high temperatures. Extensive physical characterizations show that under negative potentials, BBO pre-catalysts undergo irreversible structural and phase transformations, giving rise to Bi metallene with atomic-scale thickness and enlarged surface area, as supported by X-ray diffraction analysis and transmission electron microscopy (Figure 1a, and 1b). Using the fully electrochemically reduced BBO, a near-unity selectivity towards formate (FA) can be achieved at the potential of – 1.2 V vs. RHE in 0.1M KHCO3 solution with the typical H-type electrochemical cell. By coupling the state-of-the-art BiVO3 photoanode to the BBO dark cathode, FA can be generated at a of 80.0 % at a cell voltage of 2.5 V in a PEC cell. Contrarily, only < 1.0 % can be detected at 2.5 V without solar irradiation. Meanwhile, inductively coupled plasma optical emission spectrometry (ICP-OES) analysis suggests that A-site elements (Ba2+) are simultaneously released from the BBO lattice and diffuse to the electrolyte as a result of the complete reduction of BBO. The effect of Ba2+ - containing electrolytes on the CO2RR product distributions have been studied, and the results show that Ba2+ can either facilitate or impede FA production depending on both the external potential and the concentration of Ba2+ (Figure 1c). Specifically, high Ba2+ concentration and more negative potentials (i.e., 25 mM Ba2+ and -1.1 - -1.3 V vs. RHE) tend to favor HER over CO2RR due to the formation of BaCO3 precipitates, whereas low Ba2+ concentrations and more positive potentials (i.e., 2.5 and 7.5 mM Ba2+ and -0.9 - -1.1 V vs. RHE) can significantly enhance the selectivity towards FA. Density functional theory (DFT) calculations show that suitable barium ion adsorption promotes CO2-to-FA conversion by regulating the adsorption strength of *OCHO and *HCOOH intermediates. Our study utilizes both A- and B- site elements in BBO to benefit CO2 conversion, which may be extended to other perovskite electrocatalysts for CO2RR.T02-P03, T12-P02 University of Alberta | Activity | 2021-10-01 | Mengnan Zhu, Bowen Zhang, Minrui Gao, Chenyu Xu, Pengfei Sui, Zeng, H., Shankar, K., Bergens, S., Luo, J. | Bi2O3 Nanosheets Grown on Carbon Nanofiber with Inherent Hydrophobicity for High- Performance CO2 Electroreduction in a Wide Potential WindowT02-P03 University of Alberta | Publication | 2021-10-21 | Shao-Qing Liu, "Ehsan Shahini ", Minrui Gao, "Lu Gong ", Pengfei Sui, Tian Tang, Zeng, H., Luo, J. | Electronic Delocalization of Bismuth Oxide Induced by Sulfur Doping for Efficient CO2 Electroreduction to FormateT02-P03 University of Alberta | Publication | 2021-06-09 | | Facile and scalable surface functionalization approach with small silane molecules for oil/water separation and demulsification of surfactant/asphaltenes-stabilized emulsionsFacile and scalable surface functionalization approach with small silane molecules for oil/water separation and demulsification of surfactant/asphaltenes-stabilized emulsions.
