Summary: A new type of composite material, biopolymer-silica materials, is proposed as selective and effective adsorbents. A new synthesis procedure using geometrical modification of silica and mechanosorption of chitosan is applied to create chitosan-nanosilica composites (ChNS) and chitosan-silica gel composites (ChSG). The adsorption efficiency of ChNS and ChSG towards anionic dyes was analyzed and the results showed that ChNS had faster adsorption kinetics due to the silica-type effect.

Summary: In this study, hydrophobic and monolithic silica aerogels were prepared using beta-cyclodextrin, cetyltrimethylammonium bromide, and ethylene glycol as additives. The effects of these additives on the morphology and specific surface area of silica aerogels were investigated. It was found that introducing beta-cyclodextrin into the silica aerogel resulted in a more effective increase in adsorption capacity for n-hexane, carbon tetrachloride, and toluene compared to cetyltrimethylammonium bromide and ethylene glycol.

Summary: This study synthesized two types of silica aerogels and compared their morphology and lead adsorption behavior. One aerogel was aged with organic solvents (SG-OM), while the other was doped with tetraethyl orthosilicate (SG-TD). Both aerogels were highly mesoporous, but SG-OM exhibited higher surface area, pore volume, porosity, and lead removal efficiency compared to SG-TD. The results also showed that SG-OM had a higher adsorption capacity for lead compared to SG-TD. The findings suggest that aging with organic solvents resulted in an aerogel with improved properties for lead adsorption.

Summary: A spherical composite aerogel adsorbent (CA/KCB aerogel) was synthesized using calcium alginate (CA) and KMnO4 modified cotton stalk biochar (KCB) through sol-gel method. The optimized preparation parameters of CA/KCB aerogel were determined by response surface methodology and its physico-chemical properties and Pb2+ adsorption characteristics were investigated. The results showed that CA/KCB aerogel exhibited excellent Pb2+ adsorption performance with a maximum adsorption capacity of 664.6 mg/g. The adsorption process was an endothermic reaction dominated by monolayer chemisorption, and the binding of CA and KCB in the aerogel promoted the adsorption synergistically. Furthermore, CA/KCB aerogel showed promising potential as an adsorbent for heavy metal removal in electroplating wastewater treatment.

The Fe3O4@SiO2 submicrospheres exhibited superior catalytic activity in higher pH environments, with a degradation efficiency of 80% towards tetracycline hydrochloride (TC). The kinetics followed a second-order model, and reactive species scavenging experiments revealed the dominant roles of different radicals at pH 3 and pH 11.

Summary: Defects (oxygen vacancies and Ti3+) in TiO2 play crucial roles in determining band structure, light absorption, and catalytic activity. A strategy involving simultaneous crystallization and constraint reduction using NaBH4 as the reductant was reported to construct controllable defective TiO2. This approach enables defects to migrate effectively from the surface to the bulk region, with bulk defects being more stable. By adjusting the calcination temperature, the species and concentration of defects can be controlled, with an optimal temperature of 500 degrees Celsius found for NaBH4 treatment. Defective TiO2 treated at 500 degrees Celsius shows enhanced visible light absorption performance and a significantly higher removal rate of rhodamine B compared to TiO2 without oxygen vacancies.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
