In the field of piezoelectric applications, perovskite-based multifunctional composite ceramics are widely explored. The morphotropic phase boundary (MPB) regions, where dual structural phases coexist, play a crucial role in boosting ferroelectric and properties significantly. Herein, MPB-region-existent 0.7BiFeO3-0.3BaTiO3 (BFBT) ceramic is investigated under influence wt%Sn-ion incorporation at lattice sites BFBT. Specifically, composition BFBT:0.2Sn has demonstrated excellent remnant...
The emerging step (S)-scheme heterojunction systems became a powerful strategy in promoting photogenerated charge separation while maintaining their high redox potentials. However, the weak interfacial interaction limits migration rate S-scheme heterojunctions. Herein, we construct unique carbon nitride (CN) homojunction with boron (B)-doped CN and phosphorus (P)-doped (B-CN/P-CN) for hydrogen peroxide (H2O2) photosynthesis. B-CN/P-CN nanosheet composites revealed extensively tight contact,...
