“…Glucose oxidation . Saliger and coworkers studied Au/Al 2 O 3 catalyzed glucose oxidation in H 2 O 2 medium and obtained an apparent activation energy of 48 kJ/mol with a reaction order for glucose as 0.5 . These values agree well with the data reported for glucose oxidation using O 2 as oxidant, suggesting a similar reaction mechanism.…”

Conversion of biomass to chemicals provides essential products to human society from renewable resources. In this context, achieving atom‐economical and energy‐efficient conversion with high selectivity towards target products remains a key challenge. Recent developments in nanostructured catalysts address this challenge reporting remarkable performances in shape and morphology dependent catalysis by metals on nano scale in energy and environmental applications. In this review, most recent advances in synthesis of heterogeneous nanomaterials, surface characterization and catalytic performances for hydrogenation and oxidation for biorenewables with plausible mechanism have been discussed. The perspectives obtained from this review paper will provide insights into rational design of active, selective and stable catalytic materials for sustainable production of value‐added chemicals from biomass resources.

“…In this mass transfer control regime, the rate of glucose oxidation over the carbon-supported Au catalysts exceeds the reaction rate over the alumina-supported Au catalysts, which was attributed to a higher adhesion of the hydrophobic carbon support to the gas-liquid interface facilitating the oxygen mass transfer toward catalytic sites. Hydrogen peroxide (H 2 O 2 ) was also been used for the oxidation of D -glucose to sodium d-gluconate using a 0.3 % Au/Al 2 O 3 catalyst with a selectivity of 99 % at D -glucose conversions >99 % [ 120 ]. The 1 wt.% Au/ SiO 2 catalyst suspended in 30 % H 2 O 2 using ultrasound was highly active and selective for D -glucose oxidation at room temperature with an 85 % selectivity to gluconate at 100 % conversion under pH 9 [ 116 ].…”

The transition from a fossil chemical industry to a renewable chemical industry depends on breakthroughs in the research and development on the most promising alternatives. Biomass is such a class of renewable raw carbon materials for the production of fuels and chemicals, with growing interest among researchers aiming to achieve global sustainability. Catalytic oxidation of biomass can lead to multiple products, and the challenge is to direct the reaction pathways to the desired products. Organic acids are among the listed "platform molecules," which have the potential to be further converted into high-value-added chemicals. In this chapter, various pathways are reviewed for catalytic oxidation of a variety of biomass to produce value-added organic acids.

“…At present there is a pressing need to replace traditional chemical processes that use non-renewable raw materials (n-RRM, usually petroleum derivatives) and high amounts of energy, for clean processes that use RRM and reduce energy consumption [1,2]. Furthermore, by using industrial subproducts as RRM, a drastic decrease in environmental pollution and its negative impact on the environment is achieved [3][4][5][6].…”
