Summary: A base-free and redox neutral approach has been developed for the selective breaking of aryl ether bond in a lignin model compound mimicking a 13-O-4 linkage. Palladium-loaded metal-organic framework serves as a catalyst for dehydrogenation of benzylic alcohol moiety followed by hydrogenolysis of the ether bonds, eliminating the need for an external hydrogen source.

Summary: In this study, catalytic hydrogenolysis of organosolv poplar lignin was conducted using NiCu/C catalysts in ethanol/isopropanol solvent, achieving high yields of phenolic monomers. The introduction of Cu in catalysts promoted the hydrogen donor process of the solvent and facilitated the cleavage of lignin linkages, resulting in decreased molecular weight of bio-oil. The possible lignin dimer type structures were proposed and identified by MALDI-TOF MS, providing a better understanding of NiCu/C catalyzed lignin depolymerization.

Summary: This perspective discusses the key lessons learned from a program aiming to selectively deoxygenate cellulose-derived carbohydrates, with a focus on noneliminative mechanisms and the use of fluoroaryl borane catalysts. The control of substrate and catalyst over the deoxygenation process is crucial, and the lessons from this catalysis program can be applied to other important problems in catalysis and selectivity.

Summary: It was discovered that lignin beta-O-4 ketone models can undergo hydrogenolysis smoothly through light-induced water-donating transfer hydrogenation, which serves as an example of using water as a cheap and eco-friendly hydrogen transfer reagent for lignin beta-O-4 ketone models under catalyst-free conditions. Preliminary mechanistic investigations suggest that the formation of acetophenone radicals is involved in the mechanistic pathway.

Summary: C-O hydrogenolysis can be selectively activated by transition metal phosphides, such as Ni2P and Ni12P5, which show higher selectivities toward hindered C-O bonds compared to pure Ni catalysts. In this study, DFT calculations were used to investigate other transition metal phosphides' selectivity towards hindered C-O activation. Results showed a nearly ubiquitous shift in selectivity towards hindered C-O activation for all the phosphides compared to their pure metal counterparts, with Ni2P and Pd2P predicted to exhibit high selectivity towards 3C-O activation. The selectivity shifts can be attributed to the electronegativity of the metal and charge transfer between P and nearby metal atoms.

Summary: The conversion of lignin into value-added chemicals is an important pathway for sustainable development. In this study, an AlPyOx support synthesized using phytic acid as the phosphorus source and pore former, along with Ni loading, exhibited high catalytic activity for the conversion of lignin model compounds to high-value-added chemicals under mild conditions. The unique activity of Ni/AlP0.5Ox can be attributed to the interaction between metallic Ni and AlP0.5Ox, as well as the unique adsorption of substrates on the carrier. Lignin can also be degraded over Ni/AlP0.5Ox, yielding identified monomers.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
