Special Issue Information

Dear Colleagues,

Photo-/electrocatalysis plays a pivotal role in bridging solar/electrical energy and valuable chemicals, further paving the way for renewable energy utilization and environmental protection. More specifically, some key reactions, such as hydrogen evolution reaction (HER), oxygen evolution reaction (OER), oxygen reduction reaction (ORR), nitrogen reduction reaction (NRR), and CO2 reduction reaction (CO2RR), should be carefully investigated to achieve an ideal water cycle, nitrogen cycle, and carbon cycle for sustainable energy conversions. For this purpose, cutting-edge research should focus on developing the corresponding nanosystems and nanocatalysts. Accordingly, this Special Issue mainly focuses on advanced photo-/electrocatalytic systems including water electrolyzers, fuel cells, metal–air batteries and degradation of organic pollutants, together with effective catalyst design and catalytic mechanism development. Topics of interest include but are not limited to anything from nanomaterials to devices, from freshwater to seawater, and from experimental efforts to theoretical calculations, which may substantially contribute to (i) identifying reasonable ‘structure–activity’ for catalysts and (ii) constructing long-lasting systems for practical application.

The development of high-efficiency and low-cost catalysts toward hydrogen evolution reaction (HER) is essential for promoting the industrial water electrolysis for hydrogen production. In this work, a novel Fe3C/Ni3ZnC0.7 heterostructured nanoparticle supported on carbon nanotube is synthesized by a two-step sintering method. It is found that the density of electron state of Ni sites in Ni3ZnC0.7 is optimized and the electrical conductivity of material is greatly enhanced by the interfacial electron coupling between Fe3C and Ni3ZnC0.7. In addition, the abundant interfacial active sites of Fe3C/Ni3ZnC0.7 are exposed due to the support effect of carbon nanotubes. The prepared Fe3C/Ni3ZnC0.7 material shows excellent HER performance, delivering a low overpotential of 187 mV at a current density of 10 mA cm−2 and retains continuous operation for at least 200 h in alkaline environment. This work provides a new perspective for the design of high-performance electrocatalysts for water electrolysis. Full article

Advanced ceramics are known for their lightweight, high-temperature resistance, corrosion resistance, and biocompatibility. They are crucial in energy conversion, environmental protection, and aerospace fields. This review highlights the recent advancements in ceramic matrix composites, high-entropy ceramics, and polymer-derived ceramics, alongside various fabrication techniques such as three-dimensional printing, advanced sintering, and electric-field-assisted joining. Beyond the fabrication process, we emphasize how different processing methods impact microstructure, transport properties, and performance metrics relevant to catalysis. Additive manufacturing routes, such as direct ink writing, digital light processing, and binder jetting, are discussed and normalized based on factors such as relative density, grain size, pore architecture, and shrinkage. Cold and flash sintering methods are also examined, focusing on grain-boundary chemistry, dopant compatibility, and scalability for catalyst supports. Additionally, polymer-derived ceramics (SiOC, SiCN, SiBCN) are reviewed in terms of their catalytic performance in hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, and CO2 reduction reaction. CeO2-ZrO2 composites are particularly highlighted for their use in environmental catalysis and high-temperature gas sensing. Furthermore, insights on the future industrialization, cross-disciplinary integration, and performance improvements in catalytic applications are provided. Full article
