The development and design of electrode materials with an excellent catalytic activity and cyclic stability have significant importance for the further realization of large-scale applications of dye-sensitized solar cells (DSSCs) and hydrogen evolution reaction (HER).Herein,a facile and efficient method was used to introduce the melamine spong,which remarkably improved the dispersion of telluride.Benefiting from the synergistic effect of different components,the nanocomposite shows excellent catalytic performance.As electrode,the catalysts achieved a high power conversion efficiency (PCE) of 7.2% in solar cell,and exhibited an outstanding Tafel slope of 99 mV dec-1 in electrochemical water splitting.This work not only develops a highly efficient hybrid electrocatalyst,but also provides a promising approach to perform as multifunctional catalysts in HER,triiodide reduction reaction,and in advanced clean energy production systems.
