Recent advances in tunable metal–support interactions for enhancing the photocatalytic nitrogen reduction reaction

Abstract

Ammonia (NH3), as an important foundational chemical and green hydrogen energy carrier, plays an indispensable role in the development of human society. However, it is evident that the traditional process...

Advances in morphology-controlled alumina and its supported Pd catalysts: synthesis and applications

“…The specific preparation method significantly affects the activity, selectivity, and stability of SMCs. In addition, as extensively reported, 39,97–100 particular metal–support interactions (MSIs), i.e. , metal structural change, charge transfer, and molecular adsorption regulation, often confer superior catalytic performances to SMCs when compared to their pure metal nanoparticle counterparts.…”

The biological response of pH-switch-based gold nanoparticle-composite polyamino acid embolic material

“…28,29 The solution was concentrated to 3 mL under reflux at 50 °C; then, an equal volume of 1 × 10 −3 mol L −1 L-cysteine solution was added. 30,31 The mixture was heated at 90 °C for 30 minutes and immediately cooled in an ice bath for 10 minutes, 32 to ultimately obtain pink, soluble gold nanoparticles (Au NPs) 14,15 (Fig. 1B).…”

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

“…2,3 Fortunately, a promising technology to overcome the current restrictions of the Haber−Bosch process is photocatalytic nitrogen fixation, which produces ammonia under ambient conditions. 4 The artificial production of ammonia through the photocatalytic process requires only solar energy and water, so it is sustainable and environmentally friendly. 5,6 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.…”

“…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.…”
