日本大阪大学的一个研究小组开发出一种新的光催化技术,可在阳光的照射下,利用磷酸(H3PO4)和无金属粉末催化剂,通过H2O2水溶液(双氧水)生成氢气(H2)。研究小组发现,由于催化剂无金属,H2O2不会分解,且H2O2和H3PO4还会通过氢键形成稳定的络合物,能抑制H2O2还原,并促进H+还原。因此将H3PO4和无金属粉末催化剂加入H2O2水溶液中,照射太阳光(可见光)可以生成H2。H3PO4长期...
近日,美国田纳西大学等科研机构的研究人员在Nature Plants上发表了题为“Physiological and evolutionary implications of tetrameric photosystem I in cyanobacteria”的文章,对蓝藻四聚体光系统Ⅰ的生理和进化意义进行了深入研究。光合作用可以将光能转换成化学能。光系统Ⅰ(Photosystem Ⅰ,PSI)和...
