“…14 Specifically, biochar produced during the pyrolysis of agricultural by-products is of serious importance for employment as a low-cost adsorbent for the adsorption of a wide range of industrial contaminants from water. 15,16 In previously reported literature, various adsorbent materials (including aminefunctionalized magnetic biochar, 17 polyaniline -TiO 2 hydrate, 18 nitrogen-doped porous carbon, 19 heteroatom-doped carbon materials, 16,[20][21][22] coffee shells, 6 Pisum sativum pods, 23 rubber sludge-derived activated carbon, 24 acid-modified waste fungal biomass, 25 and natural peach gum polysaccharide based adsorbents 26,27 ) were employed for the effective remediation of hexavalent chromium from the aquatic environment.…”

“…70 Moreover, the easily tuned porosity and surface functionality of the char make it a promising platform for the preparation of various functional carbon materials, which can be applied in many interesting fields. A number of functional carbon materials have been prepared via the functionalization of char, and their applications can be found in the fields of catalysis, 71 energy storage, 72 pollutant removal, 73 and CO 2 capture. 74 Bio-oil produced from either pyrolysis or hydrothermal conversion of lignocellulosic biomass has been regarded as a sustainable energy fuel because its combustion generates much lower amounts of GHG than those of conventional fossil fuels.…”

Lignocellulosic biomass is increasingly recognized as a carbon-neutral resource rather than an organic solid waste nowadays. It can be used for the production of various value-added chemicals and biofuels like bio-oil. However, the undesirable properties of bio-oil such as chemical instability, low heating value, high corrosivity, and high viscosity are greatly restricting the utilization of bio-oil as a drop-in fuel. As a consequence, bio-oil should be upgraded. Recently, several emerging methods, such as electrocatalytic hydrogenation, atmospheric distillation, and plasma-assisted catalysis, have been developed for improving the bio-oil quality under mild conditions. Here, we overview the new knowledge on the molecular structure of lignocellulosic biomass gained over the past years and discuss the future challenges and opportunities for further advances of the bio-oil production and upgrading from lignocellulosic biomass. The development of sustainable biomass resource recycle systems with improved efficiency and minimized environmental impacts is analyzed in details. Also, their environmental impacts and sustainability are evaluated. Lastly, the remaining knowledge gaps are identified, and the future research needs that may lead to massive production of biofuels from lignocellulosic biomass are highlighted.

“…The World Health Organization (WHO) stipulates that the maximum allowable value of Cr(VI) in drinking water is 50 μg/L [ 4 ]. Traditional treatment methods, such as membrane separation [ 5 ], chemical reduction [ 6 ], adsorption [ 7 , 8 ], as well as plasma method [ 9 ], have been used to address Cr(VI) in wastewater. Currently, many materials (such as graphene, MXene, microalgal, etc.)…”

As one of the hazardous heavy metal ion pollutants, Cr(VI) has attracted much attention in the sewage treatment research field due to its wide distribution range and serious toxicity. In this paper, cellulose fibers were prepared by wet spinning and followed by freeze drying, resulting in large porosity. Subsequently, in-depth sulfhydryl modification was applied with cellulose fibers for efficient and rapid adsorption of Cr(VI). The maximum adsorption capacity of sulfhydryl-modified cellulose fibers to Cr(VI) can reach 120.60 mg g−1, the adsorption equilibrium can be achieved within 300 s, and its adsorption rate can reach 0.319 mg g−1 s−1. The results show that the in-depth sulfhydryl-modified cellulose fibers perform excellent adsorption capacity for chromium, and are also available for other heavy metal ions. At the same time, the low cost and environmentally friendly property of the as-synthesized material also demonstrate its potential for practical usage for the treatment of heavy metal ion pollution in waste water.
