Performance Exploration of Ni-Doped MoS in CO Hydrogenation to Methanol.

The preparation of methanol chemicals through CO and H gas is a positive measure to achieve carbon neutrality. However, developing catalysts with high selectivity remains a challenge due to the irreversible side reaction of reverse water gas shift (RWGS), and the low-temperature characteristics of CO hydrogenation to methanol. In-plane sulfur vacancies of MoS can be the catalytic active sites for CHOH formation, but the edge vacancies are more inclined to the occurrence of methane.

Mussel Inspired Trigger-Detachable Adhesive Hydrogel.

Adhesion to many kinds of surfaces, including biological tissues, is important in many fields but has been proved to be extremely challenging. Furthermore, peeling from strong adhesion is needed in many conditions, but is sometimes painful. Herein, a mussel inspired hydrogel is developed to achieve both strong adhesion and trigger-detachment.

Polysaccharide-Based Chiral Stationary Phases on Gold Nanoparticles Modified Silica Beads for Liquid-Phase Separation of Enantiomers.

Au nanoparticles (AuNPs) (10-15 nm in size) were prepared and deposited on the surfaces of silica particles functionalized using 3-aminopropyltriethoxysilane as the seeds under mild conditions. Then, Au seeds grew further and formed nanosheets by the method of gold chloride hydrate reduction. 3, 5-dimethylphenyl isocyanate derivative of cellulose as chiral selector was coated on the surfaces of SiO2/Au.

Cellulose type chiral stationary phase based on reduced graphene oxide@silica gel for the enantiomer separation of chiral compounds.

The graphene oxide (GO) was covalently coupled to the surfaces of silica gel (SiO ) microspheres by amide bond to get the graphene oxide@silica gel (GO@SiO ). Then, the GO@SiO was reduced with hydrazine to the reduced graphene oxide@silica gel (rGO@SiO ), and the cellulose derivatives were physically coated on the surfaces of rGO@SiO to prepare a chiral stationary phase (CSP) for high performance liquid chromatography. Under the optimum experimental conditions, eight benzene-enriched enantiomers were separated completely, and the resolution of trans-stilbene oxide perfectly reached 4.
