Abstract Background Lignin materials are abundant and among the most important potential sources for biofuel production. Development of an efficient lignin degradation process has considerable production a variety chemicals, including bioethanol. However, using current methods is inefficient. Given their immense environmental adaptability biochemical versatility, bacterial could be used as valuable tool rapid lignin. Kraft (KL) polymer by-product pulp paper industry resulting from alkaline...
Achieving high selectivity and conversion efficiency simultaneously is a challenge for visible-light-driven photocatalytic CO2 reduction into CH4 . Here, facile nanofiber synthesis method new defect control strategy at room-temperature are reported the fabrication of flexible mesoporous black Nb2 O5 catalysts that contain abundant oxygen-vacancies unsaturated Nb dual-sites, which efficient towards production The oxygen-vacancy decreases bandgap width from 3.01-2.25 eV, broadens...
Kraft lignin (KL) is the major pollutant in black liquor. The bacterial strain Pandoraea sp. B-6 was able to degrade KL without any co-substrate under high alkaline conditions. At least 38.2 % of chemical oxygen demand and 41.6 color were removed 7 days at concentrations from 1 6 g L(-1). optimum pH for degradation 10 temperature 30 °C. greatest activities 2,249.2 U L(-1) manganese peroxidase 1,120.6 laccase detected on third fifth day 10, respectively. Many small molecules, such as cinnamic...
Lignin separation from natural lignocellulose for the preparation of lignin nanoparticles (LNPs) is often challenging owing to recalcitrant and complex structure lignocellulose. This paper reports a strategy rapid synthesis LNPs via microwave-assisted fractionation using ternary deep eutectic solvents (DESs). A novel DES with strong hydrogen bonding was prepared choline chloride, oxalic acid, lactic acid in 1:0.5:1 ratio. Efficient rice straw (0.5 × 2.0 cm) (RS) realized by under microwave...
In the present work, water sorption behaviors at different temperatures ranging from 20 to 80 °C were monitored in a model Novolac cured epoxy resin (EP) and its esterfied ramifications (with CH3COO, CH3CH2CH2COO, C6H5CH2COO side groups referred as EPA, EPB, EPP, respectively). light of gravimetric measurements positron annihilation lifetime spectroscopy, mechanism was established, which suggested that equilibrium content thermodynamically controlled, while diffusion process kinetically...
Abstract Transition metal and oxide heterojunctions have been widely studied as bifunctional oxygen reduction/evolution reaction (ORR/OER) electrocatalysts for Zn‐air batteries, but the dynamic changes of transition oxides interface during catalysis are still unclear. Here, electrocatalyst Co─Co 2 Nb 5 O 14 is reported, containing lattice interlocked Co nanodots nanorods, which construct a strong metal‐support interaction (SMSI) interface. Unlike recognition that metals mainly serve ORR...
The emerging transition metal-nitrogen-carbon (MNC) materials are considered as a promising oxygen reduction reaction (ORR) catalyst system to substitute expensive Pt/C catalysts due their high surface area and potential catalytic activity. However, MNC easy be attacked by the ORR byproducts that easily lead deactivation of metal active sites. Moreover, loading affects mass transfer stability, but low delivers inferior Here, new strategy designing ZrO2 quantum dots N-complex dual...
Heavy metals are considered a class of contaminant that can accumulate in the food chain and thus must be removed from contaminated media. by electrocoagulation, electroflotation, electrodialysis, capacitive deionization, so on. Among methods to remove heavy metals, deionization is one most attractive metal ions without using large volume chemicals producing high number containing solid wastes. In this study, after brief introduction mechanism we focus on materials have been developed as...
Abstract The strain Comamonas sp. B‐9 was isolated from steeping fluid of erosive bamboo slips derived Kingdom Wu during the Three‐Kingdoms Dynasty ancient China (A.D. 220–280). It could be used to treat black liquor (BL) with high‐alkaline pH and an initial chemical oxygen demand (COD) 18,000–25,000 mg L −1 , without addition other carbon nitrogen sources. results revealed that B–9 capable reducing COD, color, lignin content BL by up 56.8, 35.3, 43.5%, respectively. High levels laccase,...
The SWNT or graphene can draw electrons from the nitrogen species in adenine to form pyrrolic/graphitic-N-type groups as ORR active sites, similar with that of N-doped carbon materials, offering an opportunity develop a class new catalysts.
