“…We have previously reported on the use of a Cu‐Zn alloy nanopowder catalyst in ethanol at 120 °C and 70 bar H 2 81 and a Cu20PMO catalyst in ethanol at 120 °C and 50 bar H 2 82 . Other notable examples include the use of Pt/MCM‐41 83 , Pt/CeO 2 ‐ZrO 2 84 , PtSn/Al 2 O 3 85 and Ir‐ReOx/SiO 2 86 at mild reaction conditions 87 .…”

Diamines are important industrial chemicals. In this paper we outline the feasibility of lignocellulose as a source of diolcontaining molecules. We also illustrate the possibility of turning these diols into their diamines in good to excellent yields. Central to these transformations is the use of commercially available Raney Ni. For diol formation, the Raney Ni engages in hydrogenation and often also demethoxylation, that way funneling multiple components to one single molecule. For diamine formation, Raney Ni catalyzes hydrogen-borrowing mediated diamination in the presence of NH 3 .

In this work, an S-doped biochar-supported CuInS2 quantum dot-sensitized Bi2MoO6 hierarchical flower (CIS@BMO@SL) was prepared using a bottom-up technique. The partial thermal reduction of CuInS2 quantum dot-sensitized Bi2MoO6 successfully fabricated a dual heterojunction, which is composed of CuInS2/Bi2MoO6 Z-scheme and Bi/Bi2MoO6 Mott–Schottky heterojunctions. The dual heterojunction was identified by X-ray photoelectron spectroscopy (XPS) and high-resolution transmission electron microscopy. Under the synergistic effect of the dual heterojunction, the electronic kinetics was significantly improved. Furthermore, the charge transfer resistance was further reduced by S-doped biochar. Under visible light irradiation, an exceptional xylonic acid yield of 86.59% was realized by CIS@BMO@SL. In this photocatalytic system, all active oxidation species, namely, ·OH, 1O2, ·O2 –, and h+, were beneficial for producing xylonic acid. The primary role of h+ in the photocatalytic system was demonstrated via a poisoning experiment. According to XPS, the poisoning experiment, and electron spin resonance, the generation of ·O2 – reveals a Z-scheme heterojunction between CuInS2 and Bi2MoO6.

“…Despite all efforts, it remains a typical chemical process with poor E-factor and waste generation. As critically highlighted by Sels and coworkers, the instability of HMF and its derivatives drastically complicates the development of new chemical technologies [ 15 ]. Susceptibility of 2,5-functionalized C6-furanic cores to intermolecular condensation leads to contamination, which severely blocks the catalytic centers on the biomass-to-HMF conversion and on the further HMF transformation stages [ 15 , 16 ].…”

Biomass-derived C6-furanic compounds have become the cornerstone of sustainable technologies. The key feature of this field of chemistry is the involvement of the natural process only in the first step, i.e., the production of biomass by photosynthesis. Biomass-to-HMF (5-hydroxymethylfurfural) conversion and further transformations are carried out externally with the involvement of processes with poor environmental factors (E-factors) and the generation of chemical wastes. Due to widespread interest, the chemical conversion of biomass to furanic platform chemicals and related transformations are thoroughly studied and well-reviewed in the current literature. In contrast, a novel opportunity is based on an alternative approach to consider the synthesis of C6-furanics inside living cells using natural metabolism, as well as further transformations to a variety of functionalized products. In the present article, we review naturally occurring substances containing C6-furanic cores and focus on the diversity of C6-furanic derivatives, occurrence, properties and synthesis. From the practical point of view, organic synthesis involving natural metabolism is advantageous in terms of sustainability (sunlight-driven as the only energy source) and green nature (no eco-persisted chemical wastes).
