“…Synthesis of MMA via one-step oxidation and esterification of methacrolein with methanol is a green and sustainable way, which has a high atom utilization rate, no pollution, and environmental friendliness, and has attracted wide attention in recent years [6][7][8][9][10][11][12]. The construction and modification of gold catalysts have shown excellent performance in CO oxidation reactions [13,14], oxidative esterification reactions [15][16][17][18][19][20][21], and other fields. However, the alkaline sites of the support in gold-based catalysts, the particle size of gold nanoparticles, and the interaction between the support and gold nanoparticles all have a certain impact on the reaction performance.…”

The water produced during the oxidative esterification reaction occupies the active sites and reduces the activity of the catalyst. In order to reduce the influence of water on the reaction system, a hydrophobic catalyst was prepared for the one-step oxidative esterification of methylacrolein (MAL) and methanol. The catalyst was synthesized by loading the active component Au onto ZnO using the deposition–precipitation method, followed by constructing the silicon shell on Au/ZnO using tetraethoxysilane (TEOS) to introduce hydrophobic groups. Trimethylchlorosilane (TMCS) was used as a hydrophobic modification reagent to prepare hydrophobic catalysts, which exhibited a water droplet contact angle of 111.2°. At a temperature of 80 °C, the hydrophobic catalyst achieved a high MMA selectivity of over 95%. The samples were characterized using XRD, N2 adsorption, ICP, SEM, TEM, UV-vis, FT-IR, XPS, and water droplet contact angle measurements. Kinetic analysis revealed an activation energy of 22.44 kJ/mol for the hydrophobic catalyst.

Traditional esterification reactions usually take place between carboxylic acids or carboxylic acid derivatives and alcohols. How to produce ester efficiently and cleanly is an urgent problem that needs to be solved in ester industrial synthesis. The development of catalysts with high catalytic activity and a long service life is significant in this process. In this review, the recent advances of the catalysts in one-step oxidative esterification of aldehydes and alcohols with alcohols to esters are summarized, including heterogeneous (mainly Au-, Pd-, Co-, and Cu-based catalysts) and homogeneous catalysts. The preparation method, catalytic performance, and catalytic mechanism of each heterogeneous and homogeneous catalyst were introduced. Finally, we put forward the existing problems of the catalyst and provide strategies to solve them.
