“…Many Cr-free catalysts including Pd/CeZrAlO x , ZnO/HZSM-5, WO x -VO x /SiO 2 , In 2 O 3 -MO x , In/HZSM-5, Mo 2 C, Fe-doped CeO 2 , Ga 2 O 3 –Al 2 O 3 , etc., were developed with good performances. Among these catalysts, Ga is one of the potential substitutions for the toxic Cr, especially for Ga 2 O 3 , which has been recognized as an active catalyst for CO 2 -ODHP and CO 2 -ODHE (E denotes ethane). , Besides Ga 2 O 3 , most recently, GaN-based catalysts were found to be efficient for oxidative dehydrogenation of butane with O 2 and CO 2 -ODHP in our group.

Dehydrogenation of propane in the presence of CO2 (CO2-ODHP) is an important route for the synthesis of propylene and utilization of the waste CO2. In the present work, diverse GaN supported on NaZSM-5 catalysts (GaN/NaZSM-5) were prepared and applied in catalyzing CO2-ODHP. GaN could activate C–H bonds in propane and cover the medium to strong acidic sites of NaZSM-5 support, which could tune the adsorption capacities of reactant molecules and further suppress the occurrence of side reactions. The Si/Al molar ratio in GaN/NaZSM-5 impacted the propane and propylene adsorption capacities of the catalyst, which closely relates to the catalytic performances. Compared with the catalytic performances of other tested catalysts, the screened GaN/NaZSM-5 catalyst with a GaN loading of 5 wt % and the Si/Al molar ratio of 470 exhibited the best results, which probably derives from its highest propane but a low propylene adsorption capacity. In this way, propane could be strongly adsorbed on the catalyst and then activated by GaN and further dehydrogenated to propylene, which was quickly released to avoid cracking. Importantly, the catalytic performances stemmed from the strong interaction between GaN and the NaZSM-5 support via the formation of Si–O–GaN species, which was confirmed by X-ray photoelectron spectroscopy (XPS) results. The Si–O–GaN species reacted with propane to form Si–O–GaN–H species, and CO2 further reacted with Si–O–GaN–H to form the COOH intermediate and then release propylene, CO, and Si–O–GaN active site. For the titled reaction, the catalyst could initially offer 45.0% conversion of propane and 28.3% yield of propylene at 600 °C. The present work not only provides a protocol for highly conversing propane to propylene but also proposes a method for tuning acidic characters of the NaZSM-5 support, which has potential application in alkane activation.

“…Besides the common metal oxides, GaN constitutes another potential heterogeneous catalyst for oxidative dehydrogenation of propane [30,32,[117][118][119][120]. Inspired by the special strong local electrostatic polarization of GaN [121][122][123][124][125], recently, our group developed several GaNbased catalysts for C-H bond activation in the CO 2 -ODHP reaction [47,[126][127][128]. For example, Q-x (a type of SiO 2 supports with varying pore size) as supports to prepare GaN/Q-x catalysts which exhibited good to excellent catalytic activity and reusability in CO 2 -ODHP.…”

CO 2 -assisted oxidative dehydrogenation of propane (CO 2 -ODHP) is an attractive strategy to offset the demand gap of propylene due to its potentiality of reducing CO 2 emissions, especially under the demands of peaking CO 2 emissions and carbon neutrality. The introduction of CO 2 as a soft oxidant into the reaction not only averts the over-oxidation of products, but also maintains the high oxidation state of the redox-active sites. Furthermore, the presence of CO 2 increases the conversion of propane by coupling the dehydrogenation of propane (DHP) with the reverse water gas reaction (RWGS) and inhibits the coking formation to prolong the lifetime of catalysts via the reverse Boudouard reaction. An effective catalyst should selectively activate the C-H bond but suppress the C-C cleavage. However, to prepare such a catalyst remains challenging. Chromium-based catalysts are always applied in industrial application of DHP; however, their toxic properties are harmful to the environment. In this aspect, exploring environment-friendly and sustainable catalytic systems with Cr-free is an important issue. In this review, we outline the development of the CO 2 -ODHP especially in the last ten years, including the structural information, catalytic performances, and mechanisms of chromium-free metal-based catalyst systems, and the role of CO 2 in the reaction. We also present perspectives for future progress in the CO 2 -ODHP.

Catalysis is essential to modern life and has a huge economic impact. The development of new catalysts critically depends on synthetic methods that enable the preparation of tailored nanomaterials. Pulsed laser in liquids synthesis can produce uniform, multicomponent, nonequilibrium nanomaterials with independently and precisely controlled properties, such as size, composition, morphology, defect density, and atomistic structure within the nanoparticle and at its surface. We cover the fundamentals, unique advantages, challenges, and experimental solutions of this powerful technique and review the state-of-the-art of laser-made electrocatalysts for water oxidation, oxygen reduction, hydrogen evolution, nitrogen reduction, carbon dioxide reduction, and organic oxidations, followed by laser-made nanomaterials for light-driven catalytic processes and heterogeneous catalysis of thermochemical processes. We also highlight laser-synthesized nanomaterials for which proposed catalytic applications exist. This review provides a practical guide to how the catalysis community can capitalize on pulsed laser in liquids synthesis to advance catalyst development, by leveraging the synergies of two fields of intensive research.
