Preparation of hydrophobic polyvinyl alcohol aerogel via the surface modification of boron nitride for environmental remediation

A three-dimensional porous MoS2–PVP aerogel as a highly efficient and recyclable sorbent for oils and organic solvents

“…A boron nitride-modified PVA aerogel was obtained via a freezedrying method, and it possesses low density, high porosity, and outstanding adsorption capacity for various solvents. 35 MoS 2 is a layered transition metal disulfide with a graphene-like structure. 36 Its unique structure advantages gives it great prospects in the fields of catalysis, batteries, and sensors.…”

Efficient reinforcement of wet gel by embedded polymer as newly approach for silica aerogel

“…10 The drying of wet gels is conventionally performed using supercritical drying technology, which is a very energy and time-consuming process, leading in a expensive production. 11,12 The ambient pressure drying technique can also be utilized for drying the wet gel, which reduces the cost of drying step. 12 In this technique, the liquid inside the pores is evaporated, leading to replacement of the solid-liquid interface with solid-gas interface, and higher energy.…”

Novel MnS/(InxCu1-x)2S3 composite for robust solar hydrogen sulphide splitting via the synergy of solid solution and heterojunction

“…Over the past years, various strategies have been proposed for converting H2S to H2 and S. [1] Among them, the photocatalytic method, which can directly utilize abundant solar energy, has attracted considerable attention. [11][12][13][14][15] Nevertheless, the quest for suitable photocatalysts for H2 production from H2S is still a tremendous challenge as the catalyst deactivation was commonly observed during H2S splitting process. [16] Recently, metal sulfides have been explored and verified to be more suitable photocatalysts compared to oxides for splitting H2S as metal sulfides are more stable in the S-containing medium and can effectively reduce the catalyst deactivation.…”
