Small‐Crystal SAPO‐34 Preparation by Regulating Precursor Mixing Temperature for Methanol‐to‐Olefins Conversion

open access: yesCarbon and Hydrogen, EarlyView.
By tuning the initial mixing temperature from 0°C to 80°C, the crystal size of SAPO‐34 can be adjusted from micro to nanoscale, reflecting a shift from classical single‐crystal growth at low temperatures to non‐classical polycrystalline aggregation at high temperatures.

Pressure‐Enhanced CO2‐to‐CO Electroreduction on Ag‐Based Catalysts: Industrially Relevant Rates and Mechanistic Insights

open access: yesCarbon Energy, EarlyView.
Ag‐based catalysts operated under elevated CO2 pressures exhibit markedly enhanced intrinsic activity for CO formation, with OD‐Ag achieving −200 mA cm–2 and 90% FECO at −1.3 VRHE. Mechanistic analysis shows that high pressure strengthens a *COOH‐mediated pathway by increasing intermediate coverage and suppressing hydrogen evolution, establishing CO2 ...

Oxidative Fast Pyrolysis Enabling Autothermal Production of Porous Functionalized Biochar and Anhydrosugar/Phenol‐Rich Bio‐Oil From Biomass

open access: yesCarbon Energy, EarlyView.
Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.
