Recent advances in transition metal sulfide-based electrocatalysts and photocatalysts for nitrogen fixation

Advancements and opportunities in piezo-(photo)catalytic synthesis of value-added chemicals

“…170 Besides their narrow band gap and tunable band structure enabling efficient solar light absorption, their typically abundant defect structures also make them highly suitable as piezo-photocatalysts. 171,172 Based on these excellent properties, Lin et al developed a highly efficient transition metal sulfide catalyst material for the production of H 2 O 2 , that is, Cd x Zn 1Àx S nanobranches (Fig. 11a).…”

Metal sulfide-based nanomaterials for electrochemical CO2 reduction

“…By modulating the morphology and structure, the physicochemical properties of the promoter can be changed, thereby changing the catalytic activity and selectivity. 147, 148 For example, it can effectively improve the active surface area of the catalyst, increase active sites for specic needs, generate novel and exciting physical phenomena, change the adsorption strength of the catalyst on the electrolyte or CO 2 , etc. 70,72 Furthermore, this approach can tailor the microenvironments near the catalyst surface for target products.…”

Incorporation of Cu5FeS4 QDs with Abundant Oxygen Vacancy TiO2 QDs/TiO2 OVs: Double S-Scheme Photocatalysts for Effectual N2 Conversion to NH3 under Simulated Solar Light

“…As a result, the utilization of solar energy for the production of chemical fertilizers and fuels has become particularly important . The industrial production of ammonia (NH 3 ), which is carried out through the Haber–Bosch process, requires harsh conditions because the activation of non-polar dinitrogen (N 2 ) molecules with triple bonds requires very high energy. , Fortunately, a promising technology to overcome the current restrictions of the Haber–Bosch process is photocatalytic nitrogen fixation, which produces ammonia under ambient conditions . The artificial production of ammonia through the photocatalytic process requires only solar energy and water, so it is sustainable and environmentally friendly. , However, existing photocatalytic systems for nitrogen fixation generally have low efficiency, so the rational design of a photocatalytic system to boost the efficiency of ammonia production is of great importance.…”
