The latest progresses in the development of catalytic systems for the acetalization of biobased furanic compounds and biogenic ethylene glycol/glycerol are systematically summarized and discussed, with an emphasis on the reaction pathway, relationship between catalyst structures and their performance, and relevant catalytic mechanism. Moreover, the application of the acetalization strategy for protecting carbonyl groups/diol structure functionalities to improve the target products' selectivity in lignin depolymerization, 5-hydroxymethylfurfural oxidation, sorbitol dehydration, and xylose hydrogenation is also highlighted.

Materials science and nanotechnology have contributed to tailoring the properties of photocatalytic materials to significantly enhance their photoactivity and stability. Here we report the development of a well-organized nanoporous TiO<small>₂</small>-based photocatalytic reactor for water treatment. Nanoporous TiO<small>₂</small> materials were directly grown using a two-step electrochemical anodization process in ethylene glycol + 0.3 wt% NH<small>₄</small>F + 2 wt% H<small>₂</small>O. The prepared nanomaterials were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and energy-dispersive X-ray spectroscopy (EDX). To enhance the photocatalytic activity of the system, water scrubbing was incorporated to boost the presence of oxygen in the water, enhancing the electron uptake at the conduction band thus significantly reducing the electron–hole recombination and increasing the photocatalytic activity. To further enhance the efficiency and reduce the negative environmental impact of the technology, a UVA-LED assembly was used instead of the typical mercury-based UV lamps for photocatalysis. The nanoporous TiO<small>₂</small> was tested as a catalyst for the photochemical oxidation of various categories of pollutants; dye (methylene blue), and the removal of microbes such as <em>E. coli</em>. The photoreactor developed in this research work was also successfully applied and tested in real-world applications such as keeping heavily used hot-tub water clean without using harmful chemicals (chlorine, bromine, ozone, <em>etc.</em>) or expensive equipment.

Compared with traditional metal pipes, polyethylene (PE) pipes have unique advantages in terms of corrosion resistance, surface friction resistance, and service life. In this paper, aiming at an enhancement of anti-scaling and corrosion-resistant properties, as well as increased mechanical properties, PE nanocomposites have been prepared by the introduction of modified carbon nanotubes (m-CNTs) into the PE matrix. To improve the interface compatibility of the composites, the CNTs were treated with reactive tetrabutyl titanate after nitric acid oxidation, which brings about uniform dispersion of the CNTs and intimate interface interaction. As the m-CNT fraction increases, the PE crystallinity displays a slight increase. Polarized microscopy shows that the scaling on the surface of the composite material is obviously reduced compared with pure PE, because the surface free energy of the composite material decreases. Moreover, due to the good dispersion, the composites show enhanced mechanical properties. That is, by adding 1.10 wt% CNTs, the tensile stress and impact toughness of the composites are 20.76 MPa and 37.89 kJ m<small>⁻²</small>, respectively, increases of 15.0% and 11.9% compared with pure PE. This paper supports the idea that the crystallinity of the PE matrix can be improved by adding CNTs, thereby increasing the corrosion resistance and anti-scaling properties.

However, unsatisfactory cyclability and poor conductivity have been recognized as the key limitations to LDH performance. To overcome these obstacles, constructing hybrid materials as well as designing porous nanoarchitectures are efficient approaches. Herein, through controlling the sulfide ion concentration during the synthesis of CuS nanosheets and adjusting the amount of urea in the synthesis of flower-like ZnCo-LDH structures, an optimized sample with an exclusive porous texture was fabricated on nickel foam (NF) (identified as NF@CS10-ZC-LDH4) <em>via</em> two-step hydrothermal routes and then employed as a binder-less electrode for a hybrid supercapacitor.

Furthermore, we fabricated a hybrid supercapacitor (NF@CS10-ZC-LDH4//NF@AC) with NF@CS10-ZC-LDH4 as a cathode electrode and activated carbon (AC)-covered NF as an anode electrode.

Therefore, non-noble metal ORR catalysts as alternatives to Pt-based group metals (PGM) have attracted much attention. However, there is still a big gap between the performance of non-noble metal catalysts and commercial Pt/C catalysts in acidic environment.

The present review covers several of the most important homogeneously catalyzed processes and technologies which are currently used or have the potential to produce fine and bulk chemicals from 1,3-butadiene. As an example, palladium-catalyzed telomerizations provide valuable chemicals through the selective dimerization of 1,3-dienes with the simultaneous addition of various nucleophiles, which can be used for the synthesis of 1-octene, 1-octanol, and various lactones. On the other hand, direct carbonylation allows the selective introduction of functional groups onto 1,3-dienes, such as carbonyl, carboxyl or ester groups. The key to success in achieving these industrially relevant conversions of 1,3-butadiene was mainly the development of innovative efficient catalysts.
