CTAB assisted evaporation-induced self-assembly to construct imidazolium-based hierarchical porous covalent organic polymers for ReO/TcO removal.

Evaporation-induced self-assembly method (EISA) was a facile and reliable method to synthesize porous materials. Herein, we report a kind of hierarchical porous ionic liquid covalent organic polymers (HPnDNH) under cetyltrimethylammonium bromide (CTAB) assisted by EISA for ReO/TcO removal. Unlike covalent organic frameworks (COFs), which usually needed to be prepared in a closed environment or with a long reaction time, HPnDNH in this study was prepared within 1 h in an open environment.

Graphene dispersant-assisted in situ growth of Re-doped MoS nanosheets on carbon cloth and their performance for hydrogen evolution reaction.

Uniform distribution of electrochemically active transition metal compounds on carbon cloth can effective improve their hydrogen evolution reaction (HER) performance, however, harsh chemical treatment of carbon substrates is always unavoidable during this process. Herein, a hydrogen protonated polyamino perylene bisimide (HAPBI) was used as interface active agent for the in situ growth of rhenium (Re) doped MoS nanosheets on carbon cloth (Re-MoS/CC). HAPBI contains a large conjugated core and multiple cationic groups and has been shown to be an effective graphene dispersant.

Potassium promoted GdCo catalysts for highly efficient catalytic NO decomposition in presence of impurity gases at low temperature.

In order to enhance the catalytic performance of the Gd-modified CoO catalyst (GdCo) for the NO decomposition, alkali metal K was introduced as the promoter by impregnating the GdCo powder with an aqueous solution of KNO (with K/Co ratios 0.01-0.05).

Strong Structural Modification of Gd to CoO for Catalyzing NO Decomposition under Simulated Real Tail Gases.

In this paper, Gd-promoted CoO catalysts were prepared via a facile coprecipitation method for low-temperature catalytic NO decomposition. Due to the addition of Gd, the crystallite size of CoO in the GdCo catalyst surprisingly decreased to 4.9 nm, which is much smaller than most additive-modified CoO catalysts.
