Enhanced quantum yield of nitrogen fixation for hydrogen storage with in situ-formed carbonaceous radicals†
Abstract
NH3 is a potential hydrogen energy carrier. Here we use alcohols as hole scavengers to investigate the nitrogen photofixation mechanisms including direct and indirect electron transfer processes. The t-butanol system exhibited the highest quantum yield of 36.1%, ascribing to the in situ-formed indirect electronic transmitter ˙CO2−.
