摘要:

过氧化氢(H2O2)是一种高效的绿色氧化剂,广泛应用于化学品合成、印染纺织、污水处理等领域。近年来,氢氧直接合成过氧化氢作为一种简单、环保、原子效率高的合成方法,成为一大研究热点。本文系统性地介绍了近年来氢氧直接合成过氧化氢催化剂的催化反应机理,负载金属的不同结构和性质对直接合成过氧化氢的催化性能与作用机理,重点讨论了与催化剂载体相关的载体结构、载体酸性、载体添加物、载体与金属相互作用等方面对反应活性和选择性的影响。最后对比了近年来直接合成过氧化氢用催化剂的催化性能,认为合成高选择性、高产率的催化剂仍是未来直接合成过氧化氢工业化应用的发展方向。

Abstract:

Hydrogen peroxide (H2O2) is a green oxidant with high efficiency (above 47.1% active oxygen), and is widely used in the production of fine chemicals, bleaching of textile and pulp, treatment of wastewater, and green chemical synthesis metallurgy. Recently, the direct synthesis of H2O2 (DSHP) from H2 and O2 has attracted great attention because of its environmentally friendly process and simple, atom-efficient route. In this paper, the catalytic mechanism for DSHP and the influence of catalytic performance for different structures and properties of different metals in recent years are summarized. The support acid sites, support structure, the interaction between active sites and acid sites are discussed. Finally, the catalytic performance of catalysts for DSHP in recent years are compared. It reveals that the industrial application of catalysts for DSHP with high selectivity and high productivity in the future is still the development direction.

Key words: hydrogen peroxide, direct synthesis, catalyst, noble metal catalysis, catalysts support
