Photo irradiation
WebA facile photo-irradiation method is developed to tune active sites over β-Ni(OH)2 nanosheets. Photo-irradiated β-Ni(OH)2 nanosheets possess disordered surface atoms and preferred growth of highly active crystal facets, which exhibit enhanced performance for the electrocatalytic oxygen evolution reaction. Chemical Communications HOT articles WebA photoswitch is a type of molecule that can change its structural geometry and chemical properties upon irradiation with electromagnetic radiation. Although often used interchangeably with the term molecular machine, a switch does not perform work upon a change in its shape whereas a machine does. [1] However, photochromic compounds are …
