“…Rh 2 (O 3 CCH 3 ) 4 catalyzes the stereospecific cyclopropanation of styrene by ethyl diazoacetate and is used to benchmark enantiomeric excess for asymmetric catalysts . For experimental benchmarking of oxidation catalysts, the rate of cyclooctene epoxidation with H 2 O 2 is often used . In the electrocatalysis community, Pt supported on high-surface-area carbon is widely considered to be the benchmark catalyst for overpotential in H 2 evolution and oxidation.…”

Benchmarking is a community-based and (preferably) community-driven activity involving consensusbased decisions on how to make reproducible, fair, and relevant assessments. In catalysis science, important catalyst performance metrics include activity, selectivity, and the deactivation profile, which enable comparisons between new and standard catalysts. Benchmarking also requires careful documentation, archiving, and sharing of methods and measurements, to ensure that the full value of research data can be realized. Beyond these goals, benchmarking presents unique opportunities to advance and accelerate understanding of complex reaction systems by combining and comparing experimental information from multiple, in situ and operando techniques with theoretical insights derived from calculations characterizing model systems. This Perspective describes the origins and uses of benchmarking and its applications in computational catalysis, heterogeneous catalysis, molecular catalysis, and electrocatalysis. It also discusses opportunities and challenges for future developments in these fields.

“…[18] Polyoxotungstates are a well known and efficient class of catalysts for the epoxidation of olefins with hydrogen peroxide. [19][20][21][22] Their use in combination with ionic liquids as solvents has been investigated recently. Examples are epoxidation reactions using the ammonium silicotungstate (Bu 4 N) 3 K[γ-SiW 10 O 36 (PhPO) 2 ] as the catalyst and microwave heating of the reaction mixtures [23] .…”

Several penta-and hexaalkylated guanidinium-based ionic liquids (GILs) were tested as solvents for the epoxidation of cyclooctene using the Venturello catalyst, [(C 8 H 17 , and hydrogen peroxide as the oxidant. Epoxide yields were obtained in a broad range between 13 and 79 % depending on both the anion and the substituents on the guanidinium moiety. Recycling experiments showed that the catalyst can be used at least three times. Furthermore, new guanidinium phosphotungstates with the PW 12 O 40 3-anion were synthesized and characterized. Their catalytic performance was evaluated, and GILs as well as acetonitrile were employed as the solvent. Results
