Metal-free boron-based materials exhibit remarkable performance in oxidative dehydrogenation of propane (ODHP). Rational design of boron-based catalysts requires a systematic understanding of the underlying mechanisms to constitute a knowledge base. This work provides a comprehensive view of the reaction mechanism of the boron-based ODH reaction and discusses the key features of the reaction systems, including the inhibition of deep oxidation, high olefin selectivity, and the role of water in the ODHP reaction.

Methyleugenol (ME) has been classified as a "group 2B carcinogen" by IARC. Its positional isomer methylisoeugenol (MIE) has been considered to be of "generally recognized as safe'' status by FDA. ME was more cytotoxic than MIE in cultured mouse primary hepatocytes.

Electro-reforming of organics such as alcohols into commodity chemicals and H powered by renewables is intriguing and prevailing with the remarkable renaissance of electrochemical technology. Integrating Pt/Pd with an auxiliary metal, metal oxide, and metal hydroxide are feasible strategies to design the desirable catalysts toward alcohols electro-oxidation reactions. These catalysts however have high affinity toward carbonyl intermediates that occupy and poison the active sites.

Recently, Beller and coworkers reported a study on the reversible hydrogenation of CO2 to formic acid using a Mn(I)-PN5P complex. In this paper, we performed DFT calculations to understand the mechanism for this reversible reaction occurring on the Mn-PN5P, Mn-PN3P, and Mn-PNP catalysts. Through investigating in detail two possible routes for CO2 hydrogenation to formic acid, we noticed that the production of formic acid is not thermodynamically favorable.

Understanding the reversible transformation between two isomeric states of organic molecules under external stimulation is essential for advancing single-molecule device development. Photochromic diarylethene (DAE) derivatives are promising candidates for single molecular switching elements. This study investigates the single-molecule reactions of the closed-form isomer of a DAE derivative on Cu(111) using scanning tunneling microscopy (STM).
