This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.

This review links recent advances in water electrolysis with hydrogen utilization in low‐gradient combustion systems. While hydrogen eliminates direct CO2 emissions, its environmental and economic benefits depend strongly on production pathways, system‐level efficiency, and NOx mitigation through MILD/FLOX/HiTAC combustion.

Fly ash (FA) and aluminium trihydrate (ATH) were incorporated into epoxy to enhance fire performance. Increasing FA content delayed ignition and reduced heat release, while the FA with ATH combination significantly improved thermal protection, extending the time for coated steel to reach 100°C from 183 to 646 s.
