“…Similar to the anthraquinone process, H 2 O 2 produced via direct synthesis is also contained in an alkaline solution, requiring the addition of acid promoters to stabilize the product H 2 O 2 . In addition, Br − and Cl − ions are also used to promote peroxide production activities, whereby it has been observed experimentally that the production of H 2 O 2 would not commence unless halide ions were present . Both acid promoters and the addition of halide ions are commonplace in the direct synthesis method, while the undesirable removal of these additives is often necessary to tailor the H 2 O 2 solution to different applications.…”

The production of H2O2 via the electrochemical oxygen reduction reaction (ORR) presents an attractive decentralized alternative to the current industry‐dominant anthraquinone process. However, in order to achieve viable commercialization of this process, a state‐of‐the‐art electrocatalyst exhibiting high activity, selectivity, and long‐term stability is imperative for industrial applications. Herein, an in‐depth discussion on the current frontiers in electrocatalyst design is provided, emphasizing the influences of electronic and geometric effects, surface structure, and the effects of heteroatom functionalization on the catalytic performance of commonly studied materials (metals, alloys, carbons). The limitations on the performance of the current catalyst materials are also discussed, together with alternative strategies to overcome the impediments. Finally, directions of future research efforts for the discovery of next‐generation ORR electrocatalysts are highlighted.

“…Types of solvents used are water, organic solvents, mixed systems, and IL. The catalysts usually used in biomass conversion such as organic acid, salts, solid acid catalysts, ion-exchange resin, and zeolites [40], [41]. Additional methods can also be incorporated to increase the performance of biomass conversions, such as using microwave irradiation [42] and probe ultrasonication [43].…”

Biomass has been used as a raw material to replace fossil fuel due to its abundance and renewability in recent years. The majority of biomass consists of carbohydrates such as glucose and fructose. The conversion of glucose into its derivative (i.e., 5-hydroxymethylfurfural (HMF)) opens several spaces to be studied. However, the yield of HMF is still low due to its ease of degradation into by-products and the difficulty of product separation. Therefore, ionic liquid (IL) is used as a solvent or media to avoid HMF degradation, which has high thermal stability, low toxicity, an un-flammable, wide range of solubility, physical and chemical stability. In addition, IL is recyclable, has good performance at dissolving biomass, and can act as a catalyst. Many important aspects of glucose conversion into HMF in IL as a media and catalyst can be deeply developed and investigated regarding conversion yield, which is affected by different ILs used, and conversion time. This review paper will discuss a detailed summary of the development of glucose conversion into HMF using IL.

“…In addition to providing a selective layer for one of the reaction components, the membrane can also act as a catalyst support and even be catalytically actively itself. Therefore, membrane technology is widely applied in the world of synthesis and waste treatment [ 20 , 21 , 22 , 23 , 24 , 25 ].…”

“…One of the membrane technology techniques considered to separate ions is nanostructured membrane technology. Graphene is one of the materials that has a nanostructure can be used as a thin and flexible membrane sheet with high chemical stability and high mechanical strength [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. Monolayer graphene membranes are accepted to be able to remove metal ions very effectively and efficient for wastewater due to their nanopores [ 31 , 32 ].…”

Mercury (Hg) is one of heavy metals with the highest toxicity and negative impact on the biological functions of living organisms. Therefore, many studies are devoted to solving the problem of Hg separation from wastewater. Membrane-based separation techniques have become more preferable in wastewater treatment area due to their ease of operation, mild conditions and also more resistant to toxic pollutants. This technique is also flexible and has a wide range of possibilities to be integrated with other techniques. Graphene oxide (GO) and derivatives are materials which have a nanostructure can be used as a thin and flexible membrane sheet with high chemical stability and high mechanical strength. In addition, GO-based membrane was used as a barrier for Hg vapor due to its nano-channels and nanopores. The nano-channels of GO membranes were also used to provide ion mobility and molecule filtration properties. Nowadays, this technology especially nanofiltration for Hg removal is massively explored. The aim of the review paper is to investigate Hg removal using functionalized graphene oxide nanofiltration. The main focus is the effectiveness of the Hg separation process.
