Nickel complexes as molecular catalysts for water splitting and CO2 reduction

One of the most appealing strategies to address the problems of global warming and energy shortage is to develop clean and sustainable energy source. To this end, considerable efforts have been devoted to designing well-defined catalysts for energy conversion. As an earth-abundant transition metal, nickel has been regarded to be an important catalytic center in molecular catalysts for redox reactions related to energy conversion. This Review...
