A review of boron nitride-based photocatalysts for carbon dioxide reduction

“…Since the reduction potential values for different products are very close to each other, producing the desired product is thermodynamically challenging. 17 A number of these CRRs can yield CH 4 , CH 3 OH or C 2 H 4 , which is thermodynamically more favourable than the two-electron evolution reactions (Table 1). However, the kinetics of the CO 2 reduction is sluggish, mainly owing to the fact that the CO 2 ˙ − anion radical does not start to be formed up to −1.90 V in order to reform the linear molecule of CO 2 into a bent anion radical (Fig.…”

Strategic catalyst modification for boosting CO2 concentration at electrode surface and easing selective CO2 reduction at higher potential

“…15,16 Recently, numerous reports were published on 2D Bi nanosheets (NS) having decent formate selectivity. 17–19 Nevertheless, synthesizing 2D metallic Bi NS with uniform heights is highly challenging, and direct synthesis requires an inert environment because of its low melting point and high susceptibility toward oxidation. 18 Furthermore, it is observed that after passing the potential with the maximum faradaic efficiency (FE), the FE of formate sharply drops at higher current density due to the mass transfer limitation of CO 2 , which also needs to be addressed.…”
