“…These coefficients can be used for kinetic modeling. The crystalline surface and structures have been characterized by various researchers and play a very prominent role in different applications, including heterogenous catalysis, − as shown in Table S2 (see SM). These peer-reviewed works were used to select the crystalline structure and its exposed surface.…”

This work reports the thermochemistry calculations for solid-phase periodic models of ten popular transition metal-based species. These model structures were refined to stable geometry by geometric optimization along with calculating the thermodynamic properties including enthalpy, entropy, heat capacity at constant pressure, and Gibbs free energy by DMol3 package via first-principles ab initio calculations. The temperature-dependent thermochemistry values were converted to a NASA seven-polynomial format. The behavior of different thermodynamic parameters based on temperature was investigated and their comparative analysis was done. A higher number of atoms tends to show higher thermodynamic values. Moreover, these thermodynamic values agree reasonably well with previously reported experimental and computational values. Metal copper shows higher thermodynamic values as compared to its oxide. The thermodynamic properties of lanthanum-based oxides have been newly calculated through the ab initio method. Amorphous structures reveal higher thermodynamic values compared to their crystalline counterparts. A comparison between different transition metal-based species gives a better understanding of the different crystalline structures and their surface sites. These calculated thermodynamic data and polynomials can be used for a variety of thermodynamic calculations and kinetic modeling.

“…The traditional VOC treatment technologies, such as adsorption, absorption, combustion, etc., have the problems of high energy consumption, high cost, low efficiency, etc. [7]. Multivariate statistical analysis is used in VOC treatment to accurately identify and quantify the emission sources of various types of VOCs by using multivariate statistical methods, such as Principal Component Analysis (PCA) and clustering analysis [8][9].…”

Against the background of the dual-carbon target, the treatment of volatile organic compounds (VOCs) emissions in the industrial sector, especially in the chemical industry, has become an urgent environmental issue. To provide scientific and objective guidance for technology selection, this study constructs a comprehensive evaluation model based on the combination of entropy weighting method and hierarchical analysis method for the complete progress of VOCs treatment technologies, taking into account the four main factors of environment, economy, management and technology and the thirteen secondary factors under them. The model provides in-depth quantitative analysis and evaluation of ten common VOCs end-of-pipe treatment technologies. The evaluation results show that thermal combustion, catalytic combustion, adsorption-concentration-combustion, and photocatalysis exhibit high comprehensive efficacy in VOCs emission treatment, with relative weight values of 0.1273, 0.1252, 0.1214, and 0.1184, respectively. These findings provide essential references and guidance for chemical companies in selecting suitable VOCs treatment technologies, which help to realize the win-win situation of environmental protection and economic development. This study fills the gap in evaluating VOCs emission management technologies and provides a practical decision-making tool for relevant decision makers.

“…(AOPs), technologies with the potential to oxidize/reduce a wide variety of complex organic compounds, have been used as an alternative for wastewater treatment [11] and hydrogen generation [12], highlighting the heterogeneous photocatalysis that through radiation-induced oxi-reduction reactions on the surface of mineral semiconductors (catalysts) promotes the degradation of organic pollutants, being able, in many cases, to correlate the kinetic study with theoretical models [13].…”

The need to adopt measures that reduce the persistence of pollutants in the environment is notorious, in order to promote the correct disposal and treatment of effluents. This study aimed to prepare, characterize, and evaluate the photocatalytic activity of activated charcoal obtained from the residual biomass of Chlorella pyrenoidosa microalgae for Rhodamine B (RhB) dye degradation. The samples were characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, N2 porosimetry, and zeta potential. To evaluate the photocatalytic activity, experiments were carried out in a stirred batch reactor. The activated charcoal prepared from microalgae biomass showed the better photocatalytic activity in the degradation of the RhB dye of 75.5% under ultraviolet radiation (k=0.0121 min-1), and 66.5% under visible radiation (k=0.0091 min-1), while the commercial ZnO achieved 92.5% (k=0.0158 min-1) and 16.6% (k=0.0032 min-1) for ultraviolet and visible radiation, respectively. Moreover, the activation/carbonization process used for the preparation of activated charcoal from microalgae biomass promoted changes in the structural, textural, and catalytic properties of the prepared samples.
