The post-industrial revolution world is facing two major challenges, namely an energy crisis and global warming. The hydrogenation of exhausted CO2 to fuel (closing the loop of carbon recycling) provides an energy storage solution for intermittent renewable sources, which can be then used as fuel or feedstock for consumer products; therefore, becoming a viable technological solution to current energy shortage and sustainability issues. Although many efforts have been made in relation to catalytic CO2 methanation, effectively activating the thermodynamically-stable CO2 molecule continues to be an obstacle, as it requires high temperatures and is an energy-intensive process.
The catalytic reduction of CO2 by H2 can lead to the formation of several types of products, such as CO produced through the reverse water–gas shift (RWGS) reaction, methanol generated via selective hydrogenation, and hydrocarbons formed through combination of CO2 reduction with Fischer–Tropsch (FT) reactions. Investigations into these routes reveal that the stabilization of key reaction intermediates is critically important for controlling catalytic selectivity. Precious metals, such as Pt, Rh, and Ru, supported on various oxides (e.g., Al2O3, TiO2, SiO2, CeO2, and ZrO2) are well known to promote CO2 reduction under relatively mild operating conditions; however, their high cost, as well as limited availability, restrict their practical application.
Research articles in all areas of heterogeneous catalysis including deactivation and poisoning of catalysts, microwave/ultrasonic/plasma assisted catalysis, high throughput experimentation, mechanistic studies, new reaction media (supercritical solvents, ionic liquids, etc.), preparation and modification of catalysts, reaction kinetics and engineering aspects, spectroscopic characterization, surface science, theory and modelling, transport effects (heat of mass) from both experimental and computational perspectives are encouraged. Articles focusing on bimetallic/alloy catalysts, colloidal catalysts, mesoporous materials, metal catalysts (solid, supported or not), metal oxides, self-assembled catalysts, sol–gel catalysts, supported catalysts, zeolites, perovskite, and spinel are welcome as well.

Title: CO2 hydrogenation to long chain hydrocarbons
Author: Eric van Steen
Affiliation: University of Cape Town, South Africa
Abstract: The reduction of the carbon footprint of an overall process may be achieved by the hydrogenation of CO2 provided that a hydrogen source is available which can be produced with minimal or without CO2-generation. The formation of long chain hydrocarbons in CO2-hydrogenation is attractive here, since they can be easily stored in the liquid form (or used as a fuel reducing thus the fossil fuel usage). Here, we examine thermodynamic aspects of CO2 hydrogenation and the resulting process options. We further look at the catalysts for direct CO2 hydrogenation and in particular at the phase stability of the various phases. Furthermore, the reported results in the direct CO2 hydrogenation will be compared.
