Developing an efficient catalyst that can reduce CO to economically viable products provides a pathway achieve carbon neutrality. For this purpose, we introduce and characterize boron phosphide nanotubes, class of materials allow one reach goal without costly toxic metal atoms. The tubular configuration imparts confining effect, facilitating adsorption catalytic reduction into ethanol. By calculating the transition state conditions under different charging using grand canonical potential kinetics, establish energy barriers in system at electrochemical potentials. We further elucidate kinetics mechanism entire reaction process microkinetics level predict onset be −0.30 V with Tafel slope 93.69 mV/dec. Finally, demonstrate control over concentrations intermediate species by choice pH applied potential. characterized material established chemical mechanisms guide design electrocatalysts for producing multicarbon products.
