Invited for this month's cover is the group of Haruo Kawamoto at Kyoto University (Japan). The cover picture shows the carbonization pathway of cellulose via 5-hydroxymethylfurfural as an important intermediate. Thermochemical conversion is one of the promising technologies to convert cellulose, which is the main component of lignocellulosic biomass, into biofuels and biochemicals. Understanding the molecular mechanism of thermal degradation of cellulose is important for developing efficient conversion techniques by controlling the reaction.

Reactive carbonyl species (RCS) are a class of compounds with one or more C = O structures with highly reactive electrophilic properties. This comprehensive review delves into the multifaceted role of RCS in thermally processed foods, where they serve as both crucial intermediates in the development of food color and flavor, as well as precursors of potentially harmful compounds. By exploring the carbonyl pool concept, the impact of RCS equilibrium on the formation and reduction of hazardous substances such as acrylamide, hydroxymethylfurfural, advanced glycation end-products, and heterocyclic amines was elucidated.

Achieving high product selectivity at ampere-level current densities is essential for the industrial application of electrochemical CO2 reduction. However, the operational stability of CO2 electrolyzers at large current density has long been hindered by flooding of gas diffusion layer (GDL). Herein, a new heteroarchitectural GDL is designed to overcome flooding.

The oxidation of 5-HMF to HMFCA is an important yet complex process, as it generates high-value chemical intermediates. Achieving this transformation efficiently requires the development of non-precious, highly active catalysts derived from renewable biomass sources. In this work, we introduce UoM-1 (UoM, University of Mazandaran), a novel cobalt-based metal-organic framework (Co-MOF) synthesized using a simple one-step ultrasonic irradiation method.

The photoelectrochemical oxidation of 5-hydroxymethylfurfural (HMF), a biomass-derived intermediate, to 2,5-furandicarboxylic acid (FDCA), a key building block for industrial applications, is a well-studied anodic reaction. This photoelectrochemical (PEC) conversion typically requires an electron mediator, such as TEMPO, regardless of the semiconductor used. Various electrocatalysts can also perform this reaction electrochemically, without additional organic species in the electrolyte.

Electrocatalytic synthesis of high-value chemicals has been attracting growing interest owing to its environmentally benign reaction pathways. Among these processes, the electrocatalytic reduction of nitrate (NO ) to ammonia (NH), known as NORR, and the oxidation of 5-hydroxymethylfurfural (HMFOR) stand out as two cornerstone reactions; yet, their efficiency and selectivity pose ongoing challenges. In this study, we introduce a charge manipulation approach for the design of highly efficient electrocatalysts tailored for the simultaneous coupling of NORR and HMFOR.
