| 英文摘要: |
| Composite nanomaterials composed of semiconductor and noble metals (e.g. platinum) have exhibited superior application in electrocatalysis due to the electronic coupling effect and lateral strain effect among their different components. The primary objectives in this research area include: ① to develop universal strategies for the fabrication of semiconductor-noble metal nanocomposites and to understand the mechanism behind the preparation so that the structure/morphology of the nanocomposites could be tuned more precisely; ② to reveal the electronic coupling effect and lateral strain effect among different components in the nanocomposites so that the performance of the materials could be further enhanced;③ to explore the applications of the nanocomposites in electrocatalysis. Herein, we will review the recent advances in this research field and make an expectation/evaluation for its future developments. |
