(Invited) Photoelectrochemical CO2 Reduction (CO2R) with Si- and III-V Based Systems

Abstract

One means to produce carbon-based fuels and chemicals in a sustainable manner is by means of solar photoelectrochemical (PEC) CO 2 reduction (CO 2 R). Many R&D challenges need to be addressed in order to advance this technological area toward commercial applications. This paper will focus on developing catalytic interfaces onto silicon and III-V semiconductor based systems, and exploring the impacts of various microenvironments and reaction conditions on efficiency, selectivity, and durability. Interfaces based on copper-based catalysts will be a general theme, leading to a range of multi-carbon products by means of PEC CO 2 R.
