All-inorganic Pb-free bismuth (Bi) halogen perovskite quantum dots (PQDs) with distinct structural and photoelectric properties provide plenty of room for selective photoreduction CO2. However, the efficient conversion CO2-to-CO high selectivity on Bi-based PQDs driven by solar light remains unachieved, precise reaction path/mechanism promoted surface halogen-associated active sites is still poorly understood. Herein, we screen a series nontoxic stable Cs3Bi2X9 (X = Cl, Br, I) photocatalytic...
Photocatalytic CO2 conversion into valuable solar fuels is highly appealing, but lack of directional charge-transfer channel and insufficient active sites resulted in limited reduction efficiency selectivity for most photocatalytic systems. Herein, we designed fabricated rare-earth La single-atoms on carbon nitride with La-N bridge as the center reaction. The formation was certified by spherical aberration-corrected HAADF-STEM, STEM-EELS, EXAFS, theoretical calculations. electronic structure...
Abstract Thermoelectric materials are capable of converting waste heat into electricity. The dimensionless figure-of-merit (ZT), as the critical measure for material’s thermoelectric performance, plays a decisive role in energy conversion efficiency. Half-Heusler materials, one most promising candidates power generation, have relatively low ZTs compared to other material systems. Here we report discovery p -type ZrCoBi-based half-Heuslers with record-high ZT ∼1.42 at 973 K and high...

Germanium telluride (GeTe)-based materials, which display intriguing functionalities, have been intensively studied from both fundamental and technological perspectives. As a thermoelectric material, though, the phase transition in GeTe rhombohedral structure to cubic at ∼700 K is major obstacle impeding applications for energy harvesting. In this work, we discovered that phase-transition temperature can be suppressed below 300 by simple Bi Mn codoping, resulting high performance of 773 K....

Abstract Semiconductor nanocrystals, the so‐called quantum dots (QDs), exhibit versatile optical and electrical properties. However, QDs possess high density of surface defects/traps due to surface‐to‐volume ratio, which act as nonradiative carrier recombination centers within QDs, thereby deteriorating overall solar cell performance.
