The selective hydrogenation of CO2 to value-added chemicals is attractive but still challenged by the high-performance catalyst. In this work, we report that gallium nitride (GaN) catalyzes the direct hydrogenation of CO2 to dimethyl ether (DME) with a CO-free selectivity of about 80%. The activity of GaN for the hydrogenation of CO2 is much higher than that for the hydrogenation of CO although the product distribution is very similar. The steady-state and transient experimental results, spectroscopic studies, and density functional theory calculations rigorously reveal that DME is produced as the primary product via the methyl and formate intermediates, which are formed over different planes of GaN with similar activation energies. This essentially differs from the traditional DME synthesis via the methanol intermediate over a hybrid catalyst. The present work offers a different catalyst capable of the direct hydrogenation of CO2 to DME and thus enriches the chemistry for CO2 transformations.

“…The rapid development of modern society accompanied by increasing energy consumption has led to growing CO 2 emissions as a result of fossil fuel burning, causing a series of environmental problems. [165][166][167][168][169] Therefore, the conversion of CO 2 into value-added fuels such as methanol and formate, is a promising approach to simultaneously create highly valuable products and alleviate environment issues. [170,171] Among the various CO 2 conversion strategies, the electrochemical CO 2 reduction reaction (CO 2 RR) has attracted considerable attention owing to its high conversion efficiencies and mild operating conditions.…”

The development of clean sustainable energy technologies has been significantly promoted by advances in electrocatalysts, especially for lowdimensional metallic nanomaterials (LDMNs), which have distinctive structural, physiochemical, and electronic properties, including a highly active surface area, efficient electron transfer, and rich surface unsaturated atoms. Recent advances have also revealed that surface engineering, interface engineering, and strain engineering for LDMNs can readily lead to increased surface active centers, strong synergistic effects, and electronic modulation, thus providing new approaches that greatly promote the electrocatalytic performance. In this review, the recent progress in LDMNs is highlighted in the context of their potential as electrocatalysts with superb performance for advanced electrocatalytic reactions. The latest achievements in their structural design, controllable synthesis, mechanistic understanding, and avenues for performance enhancement are illustrated. Strategies for controlled synthesis of high-quality LDMNs and discussed, and to boost the future development of LDMNs for energy-related conversion technology, future perspectives and potential challenges are also proposed.

“…7,8 Catalysts based on main group metals, including indium (In), tin (Sn), lead (Pb), and bismuth (Bi), have been experimentally identified as highly selective for the conversion of CO 2 into formate in neutral pH aqueous media. [9][10][11][12][13][14][15][16][17][18][19] However, many of the reported catalysts promote formate production with Faradaic efficiency >80% only at very negative potentials [<−0.8 V vs reversible hydrogen electrode (RHE)]. Recently, transition-metal cobalt (Co)-based catalysts with several atomic-layer thickness have been shown to be active for carbon dioxide-to-formate conversion at low overpotentials.…”

Electroreduction of CO 2 to target products with high activity and selectivity has techno-economic importance for renewable energy storage and CO 2 utilization. Herein, we report a hierarchical CuS hollow polyhedron (CuS-HP) for electrocatalytic CO 2 reduction (E-CO 2 R) in neutral pH aqueous media. Under E-CO 2 R conditions, CuS-HP undergoes structural reconstruction into sulfur-doped metallic Cu catalyst, which promotes formate production with Faradaic efficiency >90% in a wide potential range. The durability of the in situ evolved catalyst has been demonstrated by stable operation for 36 h at a formate partial current density of ∼16 mA cm −2 at −0.6 V versus reversible hydrogen electrode. Theoretical thermodynamic analysis reveals that the sulfurdoped Cu(111) facet is responsible for high formate selectivity by promoting formate production and suppressing hydrogen evolution.
