The recent advances in the development of heterogeneous catalysts and processes for the direct hydrogenation of CO2 to formate/formic acid, methanol, and dimethyl ether are thoroughly reviewed, with special emphasis on thermodynamics and catalyst design considerations. After introducing the main motivation for the development of such processes, we first summarize the most important aspects of CO2 capture and green routes to produce H2. Once the scene in terms of feedstocks is introduced, we carefully summarize the state of the art in the development of heterogeneous catalysts for these important hydrogenation reactions. Finally, in an attempt to give an order of magnitude regarding CO2 valorization, we critically assess economical aspects of the production of methanol and DME and outline future research and development directions.

“…2 shows the diffraction patterns of the particles before and after calcination. The carbon sphere was formed from aqueous glucose by hydrothermal method [35, 36], so a few crystalline peaks (2 θ = 5°–30°) are attributable to amorphous carbon before calcination. The Cu peaks indicate, the formation of elemental copper in the samples which becomes copper oxide during calcinations.…”

Homogeneous hollow CuO-ZnO-Al 2 O 3 microspheres, which were synthesised, used carbonaceous saccharide as a template by the hydrothermal treatment at 180°C. The hollow microspheres structure of composite metal oxides was characterised by the methods of X-ray powder diffraction, thermogravimetric analysis, scanning electron microscopy, transmission electron microscopy and N 2 adsorptiondesorption isothermal. In the evaluation of the hydrogenation of carbon dioxide, the synthesised hollow CuO/ZnO/Al 2 O 3 composite microspheres exhibited higher selectivity and yield of methanol than CuO/ZnO/Al 2 O 3 prepared by a co-precipitation method. An optimum yield of methanol of 15.3% with the 24.7% CO 2 per pass conversion was obtained under the reaction conditions of pressure at 3.0 MPa, space velocity at 1800 ml g cat −1 h −1 , the volume ratio of CO 2 /H 2 at 1:3 and temperature at 262°C.

“…These structures are desirable for catalyzing multistep reactions within a single unit. A typical example would be the direct conversion of synthesis gas to isoparaffins using modified Fischer–Tropsch synthesis or to dimethyl ether . In addition to shape‐selectivity, the core@shell catalysts benefit from a unique design which can prevent the loss of intermediate products via a cascade reaction, as demonstrated in Figure .…”

The term "engineered zeolitic materials" refers to a class of materials with a rationally designed pore system and active-sites distribution. They are primarily made of crystalline microporous zeolites as the main building blocks, which can be accompanied by other secondary components to form composite materials. These materials are of potential importance in many industrial fields like catalysis or selective adsorption. Herein, critical aspects related to the synthesis and modification of such materials are discussed. The first section provides a short introduction on classical zeolite structures and properties, and their conventional synthesis methods. Then, the motivating rationale behind the growing demand for structural alteration of these zeolitic materials is discussed, with an emphasis on the ongoing struggles regarding mass-transfer issues. The state-of-the-art techniques that are currently available for overcoming these hurdles are reviewed. Following this, the focus is set on core-shell composites as one of the promising pathways toward the creation of a new generation of highly versatile and efficient engineered zeolitic substances. The synthesis approaches developed thus far to make zeolitic core-shell materials and their analogues, yolk-shell, and hollow materials, are also examined and summarized. Finally, the last section concisely reviews the performance of novel core-shell, yolk-shell, and hollow zeolitic materials for some important industrial applications.
