Special Issue Information
Dear Colleagues,
The rapid increase in global carbon dioxide (CO2) emissions has led to significant concerns regarding climate change and its detrimental effects on the environment. As a result, there is a growing interest in finding innovative solutions to mitigate these emissions and develop sustainable practices. One promising approach is the catalytic valorisation of exhaust carbon, which involves the conversion of CO2 into valuable chemicals and fuels using catalytic and electrocatalytic processes. Dry reforming of alcohols or hydrocarbons for syngas production, CO2 methanation, and CO2 electrochemical reduction are valid approaches to transform CO2 emissions into valuable products, thereby reducing the environmental impact of carbon emissions and promoting a circular carbon economy. However, some challenges remain, such as the development of efficient and stable catalysts, the understanding of reaction mechanisms, and the integration of these processes into large-scale industrial technologies. In this sense, developing photocatalysts with high photo-conversion efficiency may solve the ensuing energy crisis and environmental concerns.
The choice and design of catalysts and electrode materials are key factors that determine the efficiency, selectivity, and economic viability of the valorisation process. The aim of the present Special Issue is to shed light on the possibilities and challenges of exhaust carbon valorisation and to inspire further technological innovation in this important area of research. Attention will be paid to the design of materials for CO2 capture and storage; new catalysts for CO2 conversion via dry reforming reactions for syngas production; Fischer–Tropsch synthesis for syngas valorization; hydrogen purification in terms of water–gas shift reaction (WGS) and preferential CO oxidation (PROX); and CO2 methanation. Moreover, the present issue will be devoted to new insights into photocatalytic materials (such as Titania/ceria/C3N4) and solid oxide electrolysis cells for CO2 conversion.

Title: Basic properties of ZnO, Ga2O3 and MgO – quantitative IR studies
Authors: Jerzy Podobiński; Jerzy Datka

Abstract: In our previous research we elaborated a method of determination of concentrations of basic sites O2- and OH- independently in quantitative IR studies of CO¬2 adsorption . Previous adsorption studies or TPD experiments provided only total basicity without distinction between O2- and OH-. In this study we determined the concentration of O2- and OH- on ZnO, Ga2O3¸and MgO surfaces. The basicity of ZnO and MgO was found significantly higher than that of Ga2O3. The surface of ZnO was rich in O2-, the contribution of OH- was very small, on the other hand, Ga2O3 surface contained mainly OH-. For MgO the contribution of O2- and OH- was comparable. According to IR results, only small fraction of all surface hydroxyls was sufficiently basic to react with CO2. The partial dehydroxylation changed the proportion between concentrations of O2- and OH- on oxides. We elaborated also a new method of determination total concentration of basic sites by CO2 desorption monitored by IR. For all the oxides studied the sum of concentrations of O2- and OH- determined in our quantitative IR studies was comparable with the total basicity determined in desorption experiments.
