Clivia miniata(CM), is an important ornamental plant and has been widely cultivated all over the world. However, there are no reports onClivia miniata-based porous biomass carbon (CMBC). In this study, for the first time, CM leaves were used to generate porous biomass carbon via NaOH activation. The structures and surface characteristics were determined using scanning electron microscopy, N2adsorption/desorption, TGA, FT-IR, X-ray diffraction, Raman and X-ray photoelectron spectra tests. CMBC has a large SSA (2716 m2/g) and a total pore volume of 1.95 cm3/g. To test the adsorption performance via adsorption experiments, the cationic and synthetic dye, malachite green (MG), was utilized as the adsorption model. The CMBC had a greatest adsorption capacity of 2622.9 mg/g at a pH value of 8 and had a fastest adsorption capacity of 1161.7 mg/g in the first 5 min. To explain MG adsorption into CMBC, the Freundlich isotherm and the pseudo-second-order kinetic model were used. The adsorption mechanism of MG was also investigated. After 10 cycles, the adsorption efficiency of CMBC to MG could still reach 85.3%. In summary, CMBC has excellent potential in dyeing wastewater pollution treatment.Keywords:biomass carbon;Clivia miniata;wastewater treatment;adsorption

A novel ternary nanocomposite of Fe 3 O 4 functionalized porous biomass carbon decorated by aligned polyaniline (A-PANI/Fe 3 O 4 /PBC) was successfully fabricated by hydrothermal and in situ oxidative polymerization. The morphology and structure of the composite was characterized by X-ray diffraction, fourier transform infrared spectra, scanning electron microcopy, transmission electron microscopy , X-ray photoelectron spectra and vibrating sample magnetometer . The microwave absorbing properties of A-PANI/Fe 3 O 4 /PBC composite were investigated in the frequency of 2–18 GHz. The results indicated that the A-PANI/Fe 3 O 4 /PBC composite possess excellent microwave absorbing performance, and the minimum reflection loss can be up to −44.8 dB at 10.67 GHz, effective absorbing bandwidth ( RL < −10 dB) reaches 4.69 GHz with a thickness of 2.7 mm. The excellent microwave absorbing performance of composite was mainly related to the multi-loss mechanisms, good impedance matching, synergistic and geometrical effect of porous biomass carbon, magnetic particles and aligned PANI.

With rapid advances in the portable electronics industry, the creation of microwave absorbing materials with high-performance to dissipate the unwanted electromagnetic wave is an important prerequisite. Herein, unique ternary organic-inorganic composites (C/Ni/PPy) were fabricated by hydrothermal method combined with in-situ polymerization approach. The correlation between structure, components, and microwave absorption capability is investigated in detail. The carbon matrix was prepared through a typical “carbonization-activation” procedure. Then, the PPy particles were decorated on the surface of the biomass carbon matrix incorporated with Ni particulates via an in-situ polymerization method. The microwave absorbing results suggest that the C/Ni/PPy ternary composites exhibit stronger dielectric loss and microwave absorption capabilities than C/PPy binary composites. A reflection loss of − 42.09 dB and an outstanding effective absorption bandwidth of 5.24 GHz are achieved simultaneously with a thickness of only 2.4 mm. The excellent microwave absorbing performances can be ascribed to the unique microstructure, enhanced polarization and the synergistic effects between dielectric loss and magnetic loss. The present work achieves a new paradigm to improve microwave absorption characteristics through the combination of dielectric components with magnetic materials. Furthermore, a prototype is proposed, which has broad application prospects for applications in next-generation wearable and portable electronics.

Carbon materials can act as electron transfer media to effectively enhance photocatalytic performance. In this study, carbon dots (CDs) were prepared using green tea to modify Ni 2 P/NiCo-LDH heterostructures. Benefitting from the Co-P bond formed between Ni 2 P and NiCo-LDH and biomass CDs, charge transfer was improved via dual channel. Ni 2 P and CDs acted as active sites for improving the photocatalytic performance. Owing to the synergistic process, the photoresponse capability of CDs/Ni 2 P/NiCo-LDH was significantly increased. In addition, the possible active species in the photocatalytic process are discussed. This study provides a design for ternary photocatalysts with carbon materials and phosphides.

Waste human hair was carbonized into carbon sheets by a simple carbonization method, which was studied as gas sensing materials for the first time. The effect of carbonization temperature on the structure and gas sensing properties of hair-based carbon sheet was studied by scanning electron microscope, X-ray diffraction, infrared spectrum, Raman spectrum, and gas-sensitive tester. The results showed that the carbonization temperature had a significant effect on the structure and gas sensing performance of carbon sheets, which were doped with K, N, P, and S elements during carbonization. However, the sensor of the carbon sheet does not show good selectivity among six target gases. Fortunately, the carbon sheets prepared at different temperatures have different responses to the target gases. The sensor array constructed by the carbon sheets prepared at different temperatures can realize the discriminative detection of a variety of target gases. For the optimized carbon sheet, the theoretical limit of detection of hydrogen peroxide is 0.83 ppm. This work provides a reference for the resource utilization of waste protein and the development of gas sensors.Keywords:human hair;biomass carbon material;gas-sensitive properties;carbon sheets

Biomanufacturing is an emerging technology that utilizes living organisms as production tools, with high specificity and selectivity, enabling customized production. Plant cell is a typical “factory” of biomanufacturing. Inspired by this, a novel bio-assisted strategy for preparing biomass-derived carbon@Fe 2 P composites has been proposed. For synthesis, Lemna minor L. is chosen as chassis plant to absorb Fe 3+ at first, then Fe 2 P can be generated in-situ in biomass during calcination. To reveal the transformation of Fe 2 P, the fate of Fe 3+ that absorbed by Lemna minor L. has been evolved. The carbon layers derived from the naturalized bioreactors (Lemna minor L. cells) can effectively constrain and disperse the synthesized Fe 2 P within nanoscale. The produced composite exhibits excellent charging-discharging capability that can achieve high specific capacity (≈340 mAh g −1 ) and long cycle life (2000 circles) at 1 A g −1 . These results demonstrate the green synthesis of Fe 2 P and the potential of the composite as a high-capacity and fast-charging anode. This strategy can also be used to prepare other transition metal phosphides (Co 2 P and Ni 12 P 5 ). In addition, this strategy combines the recovery and secondary utilization of metals in effluent, which is meaningful for phytoremediation.

The cobalt doped cadmium selenide/biomass carbon spheres (Co-CdSe/BCS) photocatalyst is easily prepared using a transitory hydrothermal reaction lasting 40 min. The Co-CdSe/BCS photocatalyst is constructed using the in situ growth of Co-CdSe nanodots on the surfaces of the BCS. Doped Co2+ generates an electron trap, which can capture the photoinduced electrons, resulting in the efficient separation of the photoinduced electron–hole pairs. Furthermore, the introduction of carbon spheres enhances the optical absorption property and the ability for electron transport. Results of electrochemical characterization and photoluminescence spectra demonstrate that the Co-CdSe/BCS is able to efficiently separate electron–hole pairs and inhibit their recombination. The as-synthesized samples display high efficiency for the photodegradation of methylene blue dye under visible light. This study offers a new strategy to promote photocatalytic performance of the CdSe photocatalyst.

The high purine diet could result in the increase of the level of blood uric acid , causing serious health problems such as hyperuricemia , gout, nephropathy and cardiovascular diseases. To find out a safe, cheap and super adsorption material for removing purines in stomach or pretreating high-purine beverages, we used different tissues of pomelo peel to prepare biomass carbon by drying, chemical modification and carbonization and then applied it to remove purine compounds in strong acidic solution, beer and soybean milk. The characteristic analysis of pomelo-peel-derived carbons (PPCs) indicated that the preparation methods significantly affected the structures and adsorption capacities of PPCs. Compared with the biomass carbon derived from bamboo, PPCs exhibited higher adsorption capabilities for purine compounds in strong acidic solution (adsorption rates > 99% in 15 min) and soybean milk (adsorption rates > 56% in 30 min) but slightly lower adsorption capabilities in beer (adsorption rates > 52% in 30 min). In addition, the adsorption capabilities of PPCs for purine compounds in beer and soybean milk were not obviously affected by temperatures. Therefore, PPCs are promising absorbents for applications in removing purine compounds from beverages to produce low-purine, healthier products for treating hyperuricemia. The strong adsorption capabilities of PPCs on purine compounds in strong acidic environment also provides a possibility of using the PPCs as food additives for removing purines in stomach for healthcare applications such as gout prevention after confirming their biosafety.

In order to improve the dispersion of molybdenum disulfide (MoS 2 ) and enhance the performance of MoS 2 , two alginate-derived biomass carbon-MoS 2 (BC-MoS 2 ) composites: CMB/CMS, were prepared by introducing BC during the synthesis of MoS 2 by hydrothermal. The effects of different gels, times and temperatures of the synthesized BC-MoS 2 were investigated, and the adsorption capacity for methylene blue (MB), basic fuchsin (BF) and copper ions (Cu 2+ ) was tested. The results indicated that the vertical growth of MoS 2 on the BC surface could be realized when using xero-gel, while the BC and MoS 2 were mixed uniformly when using wet-gel. Compared with MoS 2 , the hydrophilicity and water dispersibility of BC-MoS 2 were greatly improved, and BC-MoS 2 had better adsorption capacity for MB/BF/Cu 2+ (99.61/86.83/60 mg/g). The adsorption mechanism exhibits that the adsorption force of BC-MoS 2 on MB/BF is mainly based on the electrostatic force, and the adsorption on Cu 2+ comes from the electrostatic force and the Lewis soft-soft interaction. This study dramatically enriches the application of transition metal chalcogenides and provides a meaningful reference for wastewater treatment.

Fomes fomentarius (L.) J. J. Kickx (FF), a fungal hyphae causing tree decay, has confused people for many years on how to deal with it economically and efficiently. In this study, fungal hyphae from FF was first time used as the carbon source to prepare biomass carbon material (BCFF) material via a simple method including carbonization at 600 °C and sodium hydroxide activation. Notably, BCFF-Na4-700-60 (with alkali-carbon ratio of 4:1 and heated at 700 °C for 60 min) showed a large specific surface area (3352 m 2 g −1 ) and a high pore volume (2.29 cm 3 g −1 ). Moreover, the synthetic dye brilliant green (BG) was selected as the dye model to investigate the adsorption performance and mechanism. The maximum adsorption capacity of BCFF-Na4-700-60 was 3166 mg g −1 at pH value of 9, which is superior to those of the great majority of adsorbents. After ten cycles, the adsorption capacity could still be maintained at about 53% of the original value. The results of these studies indicate that biomass carbon materials modified with forest pathogen have excellent adsorption capacity and cycling stability, which could be considered as a potential adsorbent for treatment of wastewater from dyeing industry. More importantly, this rapid and effective method can be further applied to other similar fungal hyphae.

Electromagnetic absorption materials have gained increasing attention. In this study, we report NiO decorated biomass porous carbon derived from pine nut shells as a promising microwave absorbing material by a facile strategy. The NiO/biomass porous carbon (BPC) is thermally converted from Ni(OH)2/BPC with BPC as the base for precipitation. All products were characterized by XRD, Raman, and SEM techniques, which reveals that the NiO nanoflakes were uniformly self-assembled on the surface of the activated carbon. Compared with counterparts of pure Ni(OH)2 and Ni(OH)2/BPC, a large reflection loss peak of −33.8 dB at 16.4 GHz is achieved for the NiO/BPC composites, and the absorption bandwidth less than −10 dB can reach up to about 6.7 GHz (from 11.3 to 18.0 GHz) with a thickness of 8 mm. The enhanced microwave absorption properties originate from the electric/dielectric polarization and the unique NiO decorated BPC structures. The expanded interfaces, such as NiO–NiO, Ni–BPC and NiO–paraffin interfaces in the complicated porous composites, could boost the interfacial polarization as well as related relaxation which results in enhanced dielectric loss and electromagnetic absorbing properties. In addition, NiO/BPC nanocomposites exhibit comparatively better matching of permittivity and permeability. It is expected that our present investigation could provide a new possibility for biomass based fabrication of potential microwave absorbing materials.

Developing efficient and stable solid functional materials for the catalytic upgrading of biomass-based platform furanic molecules is of great significance to produce value-added chemicals and biofuels. We herein report β-zeolite (β)/biobased carbon hybrids supported Zr species towards the cascade conversion of furfural into γ-valerolactone (GVL) with high activity and favorable stability. The role and importance of carbon modifier were highlighted. The cellulose (CEL) modified Zr/β-CEL catalyst was found to be uniquely effective, leading to an increase of GVL yield from 49.3% to 81.1%. Catalyst characterizations revealed that the structural integrity of β was largely preserved using CEL as the carbon modifier, accompanied by the increased mesopore volume and pore size for better accessibility of active sites and diffusion of reactants. Simultaneously, the presence of CEL offered an appropriate ratio of Lewis and Brønsted acid sites due to the well incorporation and dispersion of Zr species, which ensured the successive transfer hydrogenation and ring-opening reactions. Kinetic studies demonstrated the positive effect of CEL modification on reducing the apparent activation energy and thereby facilitating the GVL formation. More importantly, Zr/β-CEL with enhanced structural stability also exhibited markedly higher recyclability compared with the pristine Zr/β. The understanding on the roles of carbon modifier can be employed to optimize the physicochemical properties of zeolite-based catalysts for roundly improving the catalytic reactivity of biomass-related compounds.
