Environmental pollution and energy crisis have become major challenges to sustainable development of human society. Solar-driven photocatalytic technology is regarded as an extremely attractive solution to environmental remediation and energy conversion. Unfortunately, practical applications of traditional photocatalysts are restricted owing to the poor absorption of visible light, insufficient charge separation and undefined reaction mechanism. Therefore, developing novel visible light photocatalysts and exploring their modification strategies are significant in the area of photocatalysis. Bi-based photocatalysts have attracted wide attention due to unique geometric structures, tunable electronic structure and decent photocatalytic activity under visible light. At present, Bi-based photocatalysts can be mainly classified as bismuth metal, binary oxides, bismuth oxyhalogen, multicomponent oxides and binary sulfides, and so forth. Although they can be used as independent photocatalysts for environmental purification and energy development, their efficiency is not ideal. Therefore, many efforts have been made to enhance their photocatalytic performance in the past few decades. Significant progresses in determining the fundamental properties of photocatalysts, improving the photocatalytic performance and understanding the photocatalytic mechanism in important reactions have been made benefited from the various new developed concepts and approaches. This review introduces the structural properties of Bi-based photocatalysts in detail and summarizes the design and modification strategy for improving the photocatalytic performance, including metal/ Peng Chen and Hongjing Liu contributed equally to this work.

The growth of the world's population has increased energy demand. Malaysia, as a developing country, also requires significant energy to drive economic development and address population demand. Malaysian conventional power generation system is highly dependent on natural gas, coal, and oil power systems that have had significant environmental impacts. This paper explores the energy status in Malaysia to highlight the advantages of fuel cells as an advanced alternative energy source. The discussion on energy status in Malaysia involves population situation, energy demand, energy sources, and energy policies. Then, the ability and type of fuel cells to provide this advanced alternative energy source in Malaysia are described. The prospects for introducing portable fuel cell devices and residential applications have been comprehensively described as the most relevant application for the residential sector to implement this technology in Malaysia. Highlights • A comprehensive review of fuel cell systems as a source of renewable energy for the residence sector in Malaysia is presented. • The introduction of fuel cell-based portable devices and residential applications are the most relevant applications for the residence sector in Malaysia. • The prospects for the introduction of fuel cells are discussed, including costs and maintenance, the plan and strategy, and the availability of a research center in Malaysia.

Herein, an electroactive filtration system, consisting of a Ti4O7 anode and a Pd-Cu co-modified nickel foam cathode, was developed and applied for the decontamination of ammonia from water. When assisted with an external electrical field, ClO• was generated on the surface of the Ti4O7 anode, which then reacted selectively with ammonia to generate N2. The anodic byproduct, NO3−, could also be reduced efficiently at the functional cathode to produce N2 as well. Electron paramagnetic resonance technique and radical scavenging tests synergistically verified the essential role of ClO• during the highly efficient ammonia conversion process. Relative to conventional batch systems, the developed flow-through design demonstrated enhanced ammonia conversion kinetics, thanks to the convection-enhanced mass transport. The proposed technology also showed desirable stability across a wide environmental matrix. This work provides new insights for the development of advanced and affordable continuous-flow systems towards effective decontamination of ammonia.
