Special Issue Information

Dear Colleagues,

According to the 2018 EPA national analysis agency TRI national analysis, the chemical industry is one of the most wasteful industries (14%), second only to the metal mining industry (44%). Since the industrial revolution, due to the rapid development and integration of industrial technology, humans have rapidly consumed natural resources to produce daily necessities for people’s lives, which has led to the deterioration of the earth’s overall environment. Beginning in the early 1990s, academia and industry have been promoting the concept of green chemistry and sustainable operations in an effort to reduce the environmental and health impacts caused by the production of the chemical industry. As chemists and advocates of sustainability, we must take precautions before they happen, not let it happen and then try to make up for the damage that has already been done. The use of chemical methods to design products and auxiliary processes to reduce pollution and cater to the health of our environment is the torch we should carry forward. Catalysts have always been an important part of many chemical processes, whether manually introduced or naturally occurring. There are many kinds of such catalysts, including enzymatic, photocatalytic, chemical, and so on. Although each catalyst can work under its own conditions, by finding the best combination of different catalysts, more effective methods can be developed. We can start to reverse the reversible effects and relieve the existing pain points of irreversible effects.

A flower-like TiO2-based composite (denoted as Zn-Ti-6) was prepared using a flower-like zinc oxide template for adsorption–photocatalytic degradation of high-chroma methylene blue. The reaction took place in an alkaline environment following hydrochloric acid treatment to remove the template and form TiO2-based composite. Sodium hydroxide played both roles of morphology-directing agent and reactive etchant. The possible mechanism for the formation of flower-like Zn-Ti-6 was proposed. The adsorption and photocatalytic degradation behavior of Zn-Ti-6 on methylene blue (MB) removal was also investigated. The results revealed that Zn-Ti-6 showed better adsorption and photocatalytic degradation performance than TiO2 nanoparticles owing to its much larger specific surface area, more abundant hydroxyls, and lower photoluminescence intensity. The adsorption and photocatalytic degradation data of Zn-Ti-6 were well fitted to the pseudo-second-order and pseudo-first-order kinetics models, respectively. The excellent adsorption performance of Zn-Ti-6 is largely beneficial to the subsequent photocatalytic degradation performance for high-chroma wastewater treatment. Overall, this study contributes a facile fabrication strategy for flower-like TiO2-based composite to achieve the adsorption–photocatalytic degradation of high-chroma wastewater. Full article

Catalysts, artificially or naturally generated, are often considered to be important factors in numerous chemical processes. Although each catalyst can act under its own characteristics, the efficiency of chemical interactions can be enhanced by a balanced combination of different catalysts. On the other hand, many game-theoretical results have been widely applied to seek the optimal or balanced state for efficiency regulation, resource control, portfolio allocation, and behavior simulation in modern academic literature. Based on game-theoretical approaches under actual chemical and biochemical environments, this article aims to analyze, construct, simulate, and derive the most efficient optimal or balanced combinations for a group of catalysts with different conditions and actions. In this article, a power index is proposed by simultaneously focusing on the factors and its active levels. In order to analyze the accuracy and rationality of this power index, we adopt usual axioms to offer some characterizations. In conjunction with the constructed game-theoretical results that are related to chemical and biochemical environments, this article further analyzes, verifies, and demonstrates the validity, accuracy, feasibility, plausibility, and applicability of the combination of catalysts with different conditions and actions.
