Bi2Te3 has attracted great attention because of its excellent thermoelectric (TE) performance around room temperature. However, the TE property of the n‐type Bi2Te3 is still relatively low compared to the p‐type counterpart, which seriously hinders its commercial application with a combination of the n‐type and p‐type materials. Herein, an effective process of Cl and W co‐doping is employed into the...
In article number 1802755, Chuanxin He and co‐workers develop a facile yet robust strategy for boosting the electrochemical hydrogen evolution reaction (HER) of metal phosphides by coating defective TiO2 overlayers. The abundant oxygen vacancies on the defective TiO2 are found to possess high activity for the adsorption and dissociation of water, thereby markedly facilitating the Volmer step of the...
Nonprecious transition metal phosphides (TMPs) have emerged as robust electrocalysts for the hydrogen evolution reaction (HER). However, the TMPs suffer from low activity for water dissociation, which greatly limits the efficiency for alkaline HER. Here, a facile yet robust strategy is reported to boost the HER of metal phosphides by coating defective TiO2 overlayers. The oxygen vacancies (Ov) on...
