The electrocatalytic reduction of nitrogenous waste offers a sustainable approach to producing nitrogen-containing chemicals. selective synthesis high-value hydroxylamine (NH2OH) is challenging due the instability NH2OH as an intermediate. Here, we present rational electrocatalyst design strategy for promoting electrosynthesis by suppressing competing pathways further reduction. We screen zinc phthalocyanines (ZnPc) with high energy barrier regulating their intrinsic activity. Additionally,...
Single-atom catalysts (SACs) with atomically dispersed metal sites in nitrogen-doped carbon matrices (M-N/C) have been identified as promising candidates for the electrocatalytic CO2 reduction reaction (CO2RR). However, recent studies aiming at economic viability inhibited by low faradaic efficiency (FE) and instability under high current density. Herein, we report a series of SACs derived from cyano-substituted phthalocyanines (MePc-CN) ZIFs (denoted Me-SACs (Pc)). These phthalocyanine...
The electrocatalytic 2e- oxygen reduction reaction (2e- ORR) provides an appealing pathway to produce hydrogen peroxide (H2O2) in a decentralized and clean manner, which drives the demand for developing high selectivity electrocatalysts. However, current understanding on descriptors of ORR electrocatalysts is still insufficient, limiting optimization catalyst design. Here we study catalytic performances series metal phthalocyanines (MPcs, M = Co, Ni, Zn, Cu, Mn) by combining density...
Polymer solar cells (PSCs) processed from non-halogenated solvents are favorable for large scale production. However, the photovoltaic performance of devices is generally inferior to that counterparts halogenated solvents. Herein, we report utilization 5-alkyl-4-(methylthio)thiophene (MTT) as a conjugated side chain polymeric donor achieve efficient PSCs toluene. The derived polymer PMTT56 exhibits lower energy levels than 5-alkyl-4-methoxythiophene (MOT) counterpart (PMOT39) and...
Cathode interface layers (CILs) are important for electron extraction in polymer solar cells (PSCs). Currently, the thickness of CILs is often below 15 nm due to their low mobility, which not favorable large-scale fabrication. Herein, we report a thick CIL efficient PSCs by modifying ZnO nanocrystals (NCs) film with perylene diimides functionalized amino oxide (PDINO). The combined NCs/PDINO inherits high mobility NCs and dense morphology PDINO, affording higher power conversion efficiencies...
Methyl functionalization on conjugated thiophene side chains is developed as an effective fine-tuning approach for polymeric donors, affording substantial efficiency improvement polymer solar cells processed from non-chlorinated solvents.
Zinc acetylacetonate is introduced to dope PDINO as an efficient cathode interface layer, affording higher power conversion efficiency and less sensitivity CIL thickness for organic solar cells.
