Photocatalytic hydrogen evolution from water splitting, using paper as an electron donor, was achieved upon the use of a hybrid photocatalyst of mesoporous TiO2 decorated with Ni nanoparticles. Through the involvement of a Ni cocatalyst, the separation and migration of photo-generated electrons in TiO2–Ni hybrids were significantly enhanced. The soluble paper in alkaline solution played the role of a sacrificial electron donor by reacting with hydroxyl radicals generated from hole oxidation with OH−. These findings provide an inexpensive route to drive aqueous proton reduction to hydrogen through waste biomass oxidation.

在设计的介孔TiO 2 -Ni杂化物上使用碱性纸实现光催化制氢,该介孔用常用纸作为牺牲电子供体†
通过使用装饰有Ni纳米粒子的介孔TiO 2杂化光催化剂,使用纸作为电子给体,实现了水分解产生的光催化氢。通过镍助催化剂的参与,光生电子在TiO 2 -Ni杂化物中的分离和迁移显着增强。在碱性溶液中可溶的纸张通过与来自用OH孔氧化产生羟基自由基反应起到了牺牲电子供体的作用- 。这些发现提供了一种廉价的途径,可以通过废物生物质氧化将水质子还原为氢。
