For the sustainable development of humanity, future efforts are necessary to develop effective technologies to reduce fossil fuels. Solar-driven hydrogen production from water splitting can be an attractive way to supply clean energy. However, the efficiency of the water splitting is limited by the reaction at the anode. Therefore Qiuhua Liang investigated some promising anode materials that may help improve the efficiency of the water splitting. The reaction that takes place at the anode is called oxygen evolution reaction (OER), which is often regarded as the main bottleneck in water splitting because it is a so-called four-electron transfer process. The efficiency of the OER relies heavily on the anode material. Qiuhua Liang found some anode materials that may increase the efficiency of the OER.
