Hydrogen production by water splitting and the removal of aqueous dyes by using a catalyst and solar energy are an ideal future energy source and useful for environmental protection. Graphitic carbon nitride can be used as the photocatalyst with visible light irradiation. However, it typically suffers from the high recombination of carriers and low electrical conductivity. Here, we have developed a facile mix-thermal strategy to prepare carbon black-modified graphitic carbon nitrides, which possess high electrical conductivity, a wide adsorption range of visible light, and a low recombination rate of carriers. With the help of carbon black, highly crystallized graphitic carbon nitrides with built-in triazine and heptazine heterojunctions are obtained. Improved photocatalytic activities have been achieved in carbon black-modified graphitic carbon nitride. The dye removal rate can be three times faster than that of pristine graphitic carbon nitride and the photocatalytic H 2 generation is 234 μmol h –1 g –1 under visible light irradiation.

Kapok fiber is a light, cottony, pale yellow to brown fiber obtained from Kapok fruit. The fiber is characterized by a large, hollow lumen and is generally hydrophobic due to its waxy surface. The fiber is difficult to spun into thread and it is commonly used as filling in mattresses, pillows, stuffed toys and upholstery. Compared to other natural fiber, kapok’s use is limited in application. However, it is now gaining attention in the scientific community as an important material due to its outstanding properties. This review will provide a detailed overview on the structure, composition and morphology of kapok fiber. It will also discuss the recent researches conducted on kapok fiber including its application as adsorbent material, biocomposite, biotemplate, electrode material and others.

Surface‐modified zinc ferrite nanocomposites were successfully prepared thru ultrasonic impregnation technique by taking kapok fiber as a bio‐template. This work demonstrates a fast preparation method to produce the bio‐templated ZnFe2O4 composite photocatalyst. The templating method for photocatalyst is favorable due to the benefit of a large surface area for solar harvesting activities in the photoelectrochemical (PEC) system. Comprehensive physicochemical analyses have successfully determined the unique properties of the prepared catalysts. The pure mimetic fibrous catalysts were successfully fabricated as photoelectrodes on the fluorine tin oxide substrate using electrophoretic deposition technique for PEC measurement. The ranging ratio of precursors used to prepare bio‐templated zinc ferrite catalysts shows an effect on their surface structure then influences the photocurrent density performance of PEC analysis. The ZF1 photoanode at 1:1 Zn/Fe ratio has generated the highest photocurrent density of 58 μA cm−2 at 0.7 V vs. Ag/AgCl compare to other samples in 0.5 M Na2SO4 electrolyte solution under 100 mW cm−2 light irradiation. The high photocurrent density was attributed to the enhancement in light‐harvesting properties, fine surface structure, and high charge transfer properties that correlate with the composite ratio's alteration. The bio‐templated zinc ferrite photocatalysts are a promising photoanode in PEC activities.
