[Altitude Distribution Characteristics of Farmland Soil Bacteria in Loess Hilly Region of Ningxia].

It is of great significance for the conservation of biodiversity in farmland ecosystems to study the diversity, structure, functions, and biogeographical distribution of soil microbes in farmland and their influencing factors. High-throughput sequencing technology was used to analyze the distribution characteristics of soil bacterial diversity, community structure, and metabolic function along elevation and their responses to soil physicochemical properties in farmland in the loess hilly areas of Ningxia. The results showed that:â‘  The Alpha diversity index of soil bacterial was significantly negatively correlated with elevation ( < 0.

Selective Oxidation of 5-Hydroxymethyl Furfural Coupled with H Production over Surface Sulfur Vacancy-Rich ZnInS/BiMoO Heterojunction Photocatalyst.

The construction of heterojunctions and surface defects is a promising strategy for enhancing photocatalytic activity. A surface sulfur vacancy (V)-rich ZnInS/BiMoO heterojunction photocatalyst (ZIS-V/BMO) was herein developed for the selective oxidation of biomass-derived 5-hydroxymethyl furfural (HMF) to value-added 2,5-diformylfuran (DFF) coupled with H production. The ZIS-V/BMO heterojunction consisted of BiMoO (BMO) with preferentially exposed high-index (131) facets and V-rich two-dimensional (2D) ZnInS (ZIS-V) nanosheets with preferentially exposed high-index (102) facets.

Hierarchical porous biochar from kelp: Insight into self-template effect and highly efficient removal of methylene blue from water.

Biochar is known to efficiently remove dyes especially for biochar with hierarchical pores and partial N-species. Here, a facile pyrolysis is used to yield N-doped biochar from kelp without additives, showing surface areas of 771 m/g as temperature up to 1000 °C and hierarchical small-sized mesopores (2-4 nm) and wide meso-macropores (8-60 nm). A possible self-template mechanism from inorganics is proposed to form hierarchical pore architecture in biochar and used for methylene blue (MB) removal.

Fabrication of N-doped carbons from waste bamboo shoot shell with high removal efficiency of organic dyes from water.

N-doped carbons were obtained from bamboo shoot shell via hydrothermal pretreatment under salt assistance followed by carbonization, using melamine as nitrogen source. The carbons with tubular morphology and surface areas in 406-489 m/g range were used as adsorbents for the removal of methyl orange (MO) and rhodamine B (RhB). Adsorption isotherms and kinetic fitting showed much better accordance with Freundlich model and pseudo-second-order, showing balanced capacity (q) of 50 mg/g for MO and 42 mg/g for RhB on the pristine carbons (BHC-800) at 25 °C.

From metal-organic frameworks to porous carbon materials: recent progress and prospects from energy and environmental perspectives.

Metal-organic frameworks (MOFs) have emerged as promising materials in the areas of gas storage, magnetism, luminescence, and catalysis owing to their superior property of having highly crystalline structures. However, MOF stability toward heat or humidity is considerably less as compared to carbons because they are constructed from the assembly of ligands with metal ions or clusters via coordination bonds. Transforming MOFs into carbons is bringing the novel potential for MOFs to achieve industrialization, and carbons with controlled pore sizes and surface doping are one of the most important porous materials.
