Special Issue Information

Dear Colleagues,

Carbon dioxide and its emissions represent a hot topic in global warming discussions. However, it also represents the most abundant source of carbon which is not utilized. The idea of conversion of carbon dioxide into other useful chemicals such as methanol or methane and their utilization as fuels could help with the world’s emerging energy shortage. Even though photocatalytic reduction of CO2 has been studied for many years, its exact reaction mechanism is not known, and even the reaction itself represents a challenge. This Special Issue collects original research papers, reviews, and commentaries focused on improving the knowledge of photocatalytic reduction of carbon dioxide, including new reactor design, novel photocatalysts, and especially understanding of reaction mechanisms.

1. Title: Layered Double Hydroxide (LDH) based heterojunctioned photocatalysts: An Outstanding Strategy for Efficient Photocatalytic CO2 Conversion

Abstract: Conversion of CO2 to solar fuels/chemicals is an alluring approach for the minimization the critical issues of global warming, environmental pollution, and climatic changes, induced by increased level of atmospheric CO2. In addition such conversion also benefits in term of energy chemicals, hence holding a great potential to overcome the energy crisis. Amongst various CO2 conversion strategies, photocatalytic CO2 conversion (PCC), is considered as one of the effective and sustainable approach, utilizing sunlight as a free energy source with a photocatalyst material to convert moist CO2 to useful products. Hence, development of promising and efficient photocatalysts is an essential activity for the respective scientific community to upgrade and boost the PCC research domain. Until today, metal oxides such as TiO2, ZnO etc. are categorized as standard photocatalysts because of their stabilty, abundant availability, and cheaper material. However, their performance is tethered by limited light absorption and somewhat physical properties. To overcome such barriers, recently, layered double hydroxide (LDH) offers an exciting and efficient way for PCC due to their superb adsorption and moderate photocatalytic. Several strategies like metals and non-metals doping, surface modification and nanostructures formation for LDH photocatalytic materials have been investigated. The strategy of LHD based hetero-junctions and composite photocatalysts shows an extraordinary physiochemical and electrical properties like high surface area, stability, anticorrosion capacity, photosensitizer, and excellent conductivity. Hence, LDH based hetero-junctioned photocatalysts can be an excellent approach come up with an extra ordinary performance in the field of PCC. In the present review article, a summarized survey is portrayed regarding the latest development for LDH based hetero-junctioned photocatalysts with focus of hetero-junction formation with various photocatalysts materials, influencing parameters and possible mechanism involved thereof in PCC to useful fuels and chemicals like CO, CH4, CH3OH, etc.
