BiOCl/SnS2 core-shell heterojunction is prepared by a facile and economic hydrothermal method. The obtained BiOCl/SnS2 heterojunction displays high photocatalytic activity in the degradation of Rhodamine B (RhB). The high performance is explained by the fast separation of the photoinduced electron–hole pairs promoted by the heterojunction. The cycle life of the heterojunction is also improved compared with individual BiOCl or SnS2.

The Impact

The effects of the core-shell ratio and concentration of urea formaldehyde (UF) resin-coated waterborne acrylic resin microcapsules on the optical properties, mechanical properties and liquid resistance of waterborne topcoat coatings on the surface of Tilia europaea were investigated. With the increase of microcapsule concentration, the color difference and hardness of the paint film gradually increased, the gloss and adhesion of the paint film gradually decreased, and the impact resistance and elongation at break of the paint film increased first and then decreased. With the increase of the core-shell ratio, the hardness and impact resistance of the paint film increased first and then decreased, and the adhesion of the paint film decreased gradually. Red ink had a great influence on the liquid resistance of paint film. When the core-shell ratio of UF-coated waterborne acrylic resin microcapsule was 0.58:1 and the microcapsule concentration was 10.0%, the comprehensive performance of paint film on Tilia europaea was better. The prepared self-healing microcapsules applied to the waterborne coatings committed to prolonging the service life of the paint film.
