Abstract Electrochemical synthesis of H 2 O through a selective two-electron (2e − ) oxygen reduction reaction (ORR) is an attractive alternative to the industrial anthraquinone oxidation method, as it allows decentralized production. Herein, we report that synergistic interaction between partially oxidized palladium (Pd δ+ and oxygen-functionalized carbon can promote 2e ORR in acidic electrolytes. An electrocatalyst synthesized by solution deposition amorphous Pd clusters 3 4 onto mildly...
Manganese-based aqueous batteries utilizing Mn2+ /MnO2 redox reactions are promising choices for grid-scale energy storage due to their high theoretical specific capacity, power capability, low-cost, and intrinsic safety with water-based electrolytes. However, the application of such systems is hindered by insulating nature deposited MnO2 , resulting in low normalized areal loading (0.005-0.05 mAh cm-2 ) during charge/discharge cycle. In this work, electrochemical performance various...
Pyrolyzed Fe/N/C, a promising nonprecious-metal catalyst for oxygen reduction reaction (ORR), usually relies on abundant micropores, which can host large amount of active sites. However, microporous structure suffers from severe water flooding to break the triple-phase interface where ORR occurs, especially in direct methanol fuel cell (DMFC) fed with liquid fuel. Current studies about fabrication are mainly limited Pt/C layer, mesopores and macropores concerned. Here, we successfully...
Redox mediators (RMs) play a vital role in some liquid electrolyte-based electrochemical energy storage systems. However, the concept of redox mediator solid-state batteries remains unexplored. Here, we selected group RM candidates and investigated their behaviors roles all-solid-state lithium-sulfur (ASSLSBs). The soluble-type quinone-based (AQT) shows most favorable potential best reversibility that functions well for lithium sulfide (Li2S) oxidation solid polymer electrolytes....
Ethanol is a green, sustainable, and high-energy-density liquid fuel that holds great promise for direct cells (DLFCs). However, it remains highly challenging to develop electrocatalysts selectively promote the C–C bond scission ethanol oxidation reaction (EOR). Here, we report facile synthesis of PtIr alloy core–shell nanocubes (NCs) with Ir-rich shells as effective EOR electrocatalysts. We find (100)-exposed Pt38Ir NCs one-atom-thick skin exhibit unprecedented activity, high CO2...
Silicon (Si)-based anodes are promising for next-generation lithium (Li)-ion batteries due to their high theoretical capacity (∼3600 mAh/g).

A series meshes designed as reagents, which applied Si anode battery fabrication and spontaneously prelithiate with addition. Various...
