Co3O4/C‐NFs Induced 3D Electric Field Enhancement for Dual‐Regulation of Polysulfides and Li+ Transport in Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
A nano‐framework structured Co3O4/C catalyst with 3D electric field enhancement is designed to facilitate the mass transfer of both Li⁺ and lithium polysulfides (LiPSs) in lithium–sulfur batteries (LSBs). The enhanced electric‐field–driven migration significantly accelerates sulfur reduction reaction (SRR) kinetics while suppressing the shuttle effect ...

Interfacially Coupled and Synergistic Effect of Ag/Co3O4‐C Nanocomposites for Enhanced Oxygen Reduction (ORR) and Evolution (OER) Reaction

open access: yesAdvanced Science, EarlyView.
Ag/Co3O4–C nanocomposites display well‐resolved lattice fringes and synergistic Ag/Co3O4 heterointerfaces that enhance charge transfer and active‐site exposure. The structural design enables superior bifunctional ORR/OER performance in alkaline media by promoting efficient adsorption and turnover of oxygen intermediates within an optimized ...

Biomass gasification via fast pyrolysis

open access: yes, 2016
Fast pyrolysis is the thermal degradation of biomass, by rapid heating of small particles in the absence of oxygen. The products obtained are permanent gas, condensable vapours and char. Experiments for 16 different biomass materials have shown that over 95% of the inorganic elements originally present in the biomass, are retained in the char.
