“…Given this finding, it is not quite as surprising that different product yields are observed using a Ni 3 Al catalyst distributed on glassy carbon versus a CIGS (copper, indium, gallium, selenium) based ptype photoelectrode. 10,12,13 In contrast to the above approach, we have also explored the chemistry involved in the homogeneous electroreduction of CO 2 . Presently, our main vehicle for doing this is complexes based on a MnXbpy(CO) 3 motif, which is highly selective for the conversion of CO 2 to CO.…”

Conspectus Our global society generates an unwieldy amount of CO2 per unit time. Therefore, the capture of this greenhouse gas must involve a diverse set of strategies. One solution to this problem is the conversion of CO2 into a more useful chemical species. Again, a multiplicity of syntheses and products will be necessary. No matter how elegant the chemistry is, commercial markets often have little use for a small set of compounds made in tremendous yield. Following this reasoning, the Bocarsly Research Group seeks to develop new electrochemical and photochemical processes that may be of utility in the conversion of CO2 to organic compounds. We focus on investigating proton-coupled charge transfer mechanisms that produce both C1 and carbon–carbon bonded products (C2+). In early work, we considered the reduction of CO2 to formate at electrocatalytic indium and tin electrodes. These studies demonstrated the key role of surface oxides in catalyzing the reduction of CO2. This work generated efficient systems for the formation of formate and paved the way to studies using non-copper, intermetallic electrocatalysts for the generation of C2+ species. Most notable is the efficient formation of oxalate at an oxidized Cr3Ga electrode. Oxalate has recently been suggested as a potential nonfossil, alternate organic feedstock. Separately, we have focused on the electrocatalytic effects of pyridine on the reduction of CO2 in aqueous electrolyte. These studies demonstrated that electrodes that normally yield a low hydrogen overpotential (Pd and Pt) show suppressed H2 evolution and strongly enhanced activity for CO2 reduction in the presence of pyridinium. Methanol was observed to form in high Faradaic yield at low overpotential using this system. The 6-electron, 6-proton reduction of CO2 in the presence of pyridinium was intriguing, and significant effort was placed on understanding the mechanism of this reaction both on metal electrodes and on semiconducting photocathodes. P–GaP electrodes were found to provide exceptional behavior for the formation of methanol using only light as the energy source. The pyridinium studies highlighted the role of protons in the overall reduction of CO2, stimulating our interest in the chemistry of MnBr(bpy)(CO)3 and related compounds. This complex was reported to electrochemically reduce CO2 to CO. We saw these reports as an opportunity to study the detailed nature of the proton-coupled electron transfer (PCET) mechanism associated with CO2 reduction. Our investigation of this system revealed the role of hydrogen-bonding in CO2 reduction and pointed the way for the construction of a photochemical process for CO generation using a [(bpy)(CO)3Mn(CN)Mn(bpy)(CO)3]+ photocatalyst. Based on our studies to date, it appears likely that heterogeneous systems can be assembled to convert CO2 into products that are “beyond C2 products.” This may open up new practical chemistry in the area of fossil-based replacements for both synthesis and fuels. Systems with pragmatic efficiencies are close to re...

“…Hence, the generation of CH 3 OH in aqueous PEC CRR cells is challenging due to the lack of cocatalysts for CH 3 OH production. [78][79][80][81][82] Several works on the TiO 2 -protected InP and GaP photocathodes have indicated that the oxygen vacancy-rich TiO 2 was active to catalyze the CO 2 reduction to produce CH 3 OH. Further studies on these photocathodes indicated that the oxygen vacancies (Ti 3+ position) were possible active sites for CO 2 -to-CH 3 OH conversion.…”

Carbon neutrality has become an urgent mission for the future of mankind. Powering the world with renewable energy from solar CO2 reduction represents a promising way to accomplish this target. Photoelectrochemical (PEC) CO2 reduction, integrating the merits of photocatalysis and electrocatalysis, offers an intriguing and effective approach to realizing solar fuel production and CO2 mitigation in one shot. To stimulate research efforts in PEC CO2 reduction, a comprehensive review of recent advances in this field is presented, with a special emphasis on the general design motives for the assembly of highly efficient PEC cells. First, basic principles and evaluating parameters of PEC CO2 reduction cells are introduced. Then, recent innovative PEC cells with highly active photocathodes for CO2 reduction to different target chemicals are highlighted and the material designing principles are discussed. In addition, the representative self‐biased PEC CO2 reduction cells including the tandem and artificial‐leaf configurations are also addressed. Finally, this review is concluded with remarks on the present achievements in PEC CO2 reduction to different chemicals, pointing out some effective strategies to promote the efficiencies for solar fuel production. A vision of the challenges and opportunities for how to forward PEC CO2 reduction research is further provided.

“…[157] Aside from those heterojunction catalysts based on p-Si and g-C 3 N 4 , the idea to overcome ineffective interfacial charge transfer or non-ideal optical conversion drives the research towards other not so usual junctions. The literature reports several heterocatalysts free of oxides for photochemical reactions such as MoSe 2 /ZnIn 2 S 4 , [160] black phosphorus and g-C 3 N 4 (BP/g-C 3 N 4 ), [161,162] FeCoS 2 -CoS 2 , [46] CuInSe 2 /Ni 3 Al, [163] and Au/p-GaN. [164] However, until this moment, most of those catalysts were not applied for CO 2 reduction using the PEC technique.…”

Due to their catalytic characteristics, including highly accessible active sites, excellent charge separation properties, great capability for adsorption of CO2 and H2O due to abundant surface defects, and adjustable electronic features, non‐oxide two‐dimensional nanomaterials have received great attention in areas like water splitting and carbon dioxide (CO2) reduction. There are diverse non‐oxide 2D semiconductors reported in literature, among them this review inspects closely the two‐dimensional transition‐metal dichalcogenides (TMDC), MXene materials, graphitic carbon nitride catalysts, metal‐organic frameworks (MOFs), and the heterojunctions of those. This investigation is expected to stimulate new research to improve the design and possible applications of 2D materials by strategies that involve controlling the structural, optical, and electronic properties impacting the catalysts’ activity, selectivity, and stability for successful application in the CO2 reduction or other catalytic reactions.
