Abstract Electrochemical CO 2 reduction (ECR) to value-added products is regarded as a sustainable strategy mitigate global warming and energy crisis, designing highly efficient robust catalysts essential. In this work, transition metal sulfides (TMS)-decorated CuS microflower-like structures were prepared via the one-pot hydrothermal synthesis method for ECR CO, influence of TMS doping on performance was demonstrated. Characterization performed using XRD, FESEM-EDS, N physisorption, XPS, revealing successful loading TMS, formation architectures generation sulfur vacancies. tests demonstrated that ZnS, Bi S 3 , CdS MoS improved intrinsic activity catalyst. Particularly, -CuS composite catalyst with imperfect petal-like structure showed uniform distribution edge Mo sites, which worked synergistically formed grain boundaries (GBs) undercoordinated vacancy sites in promoting activation, stabilizing * COOH adsorption, facilitating desorption, lowering barrier potential-limiting step selectivity. The achieved maximum selectivity 83.2% at –0.6 V versus reversible hydrogen electrode (RHE) high cathodic energetic efficiency 100%. At potential, maintained stable catalytic during 333-min electrolysis process. findings will offer promising avenue development production from ECR.

Native Defects Hybridization and Electronic Transport in Cu₂Se‐CuGaSe₂ Hierarchical Composites

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(46)

Published: July 30, 2024

Abstract Engineering the energy distribution of electronic defects in semiconductors can afford coexistence degenerate and nondegenerate transport behavior. By leveraging native Cu 2 Se CuGaSe phases, tunability concentration active hierarchical (1‐x)Cu Se‐(x)CuGaSe composites is demonstrated. This study found that electrical conductivity various decreases with rising temperature indicating semiconducting behavior, whereas carrier density increases temperature, which consistent non‐degenerate semiconductivity. Remarkably, this while drop increasing content for samples x ≤ 0.45 an increase activation “active” defects, sudden by 140% 109% near equimolar composition suggests formation a large lower energy. unusual behavior understood within context hybridization coexisting to form hybrid acceptor states The reported unique be leveraged development more versatile optoelectronic devices superior performance.
