Atomically distributed Al-F nanoparticles towards precisely modulating pore size of carbon membranes for gas separation.

To confront the energy consumption, high performance membrane materials are urgently needed. Carbon molecular sieve (CMS) membranes exhibit superior capability in separating gas mixtures efficiently. However, it remains a grand challenge to precisely tune the pore size and distribution of CMS membranes to further improve their molecular sieving properties.

Inspired by Wood: Thick Electrodes for Supercapacitors.

The emergence and development of thick electrodes provide an efficient way for the high-energy-density supercapacitor design. Wood is a kind of biomass material with porous hierarchical structure, which has the characteristics of a straight channel, uniform pore structure, good mechanical strength, and easy processing. The wood-inspired low-tortuosity and vertically aligned channel architecture are highly suitable for the construction of thick electrochemical supcapacitor electrodes with high energy densities.

Tailor the crystal planes of MIL-101(Fe) derivatives to enhance the activity of SCR reaction at medium and low temperature.

Mainly exposed crystal facets and controllable morphology play a key role in the final performance of the preparation of specific nanomaterials. In the present study, a metal-organic framework pyrolysis method without adding solvent modifiers was developed. By adding CO in the calcination atmosphere to change atmosphere ratio, FeO nanostructures are exposed with different crystal planes and evaluated their performance in NH-SCR reaction.

Interfacial FeC-Cu catalysts toward low-pressure syngas conversion to long-chain alcohols.

Long-chain alcohols synthesis (LAS, COH) from syngas provides a promising route for the conversion of coal/biomass/natural gas into high-value chemicals. Cu-Fe binary catalysts, with the merits of cost effectiveness and high CO conversion, have attracted considerable attention.

Effect of SCR Atmosphere on the Removal of Hg by a VO-CeO/AC Catalyst at Low Temperature.

A series of VO-xCeO/AC (noted as V-Ce/AC) catalysts were synthesized by the impregnation method, which combined the advantage of AC and V-Ce. The effects of SCR atmosphere on Hg removal were systematically investigated at low temperature. The experimental results indicated that NO had a positive effect on Hg removal.
