Abstract Clay-cellulose biocomposite (CCB) was synthesized in the present study. Spin and pressure-induced heating was applied to aggregate exfoliated clay tubules and cellulose using polyethylene glycol as an intermediate. The synthesized CCB was modified in the presence of NaOH at high temperature to obtain negative surface charge on the adsorbent. Physico-chemical properties of CCB were evaluated using different characterization techniques including Fourier transform infrared (FT-IR) and X-ra...

Abstract Carbon-based materials with a controlled pore size distribution are highly desirable to achieve fast diffusion of electrolytes and enhance supercapacitor performance. Here, we report a method to effectively control porosity of the phenol formaldehyde (PF) resin-based carbons along with pore volume and pore size distribution using a combined metal templating and physical/chemical activation approach. The combined metal templating and physical/chemical activation approach allows precise c...

The visible-light-induced photocatalytic performance of a three-dimensional (3D) hybrid composite based on carbon nano-onion (CNO)-functionalized zinc-oxide tetrapods (T-ZnO) was investigated to study the photocatalytic degradation of 2,4-dinitrophenol (DNP). The hybrid CNO-functionalized T-ZnO 3D composite was successfully developed via a facile one-step process. The CNOs, synthesized via a green route from flaxseed oil, were decorated on the surface of T-ZnO via chemical mixing. Such a hybrid ...

Visible-light-driven photocatalysts prepared using renewable resources are crucial but challenging to develop for the efficient degradation of organic pollutants, which is required to solve ever-increasing water deterioration issues. In this study, we report a visible-light-responsive photocatalyst for the efficient degradation of methylene blue (MB) as a model pollutant dye. Green-emissive carbon quantum dots (CQDs) were synthesized from pear juice via a facile, scalable, one-pot solvothermal p...

A new discrete bis-dithiolene complex, [PPh4]2[Zn(DMED)2] (1; DMED = 1,2-dicarbomethoxy-1,2-dithiolate) with sulfur-based radical character was synthesized and structurally characterized. Complex 1 is stable and exhibits a square planar geometry around the zinc metal. 1 forms nanospheres through a one-pot water-induced self-assembly in a mixture of solvents (acetonitrile–water). These nanospheres were further decorated with water-soluble carbon nanotubes (wsCNTs) through hydrogen bonding between...

The integration of electrochromic (EC) and thermochromic (TC) systems is important for realizingmultifunctional smart windows, which can adaptively control light transmittance and solar energy in response to diverse external stimuli. In this study, we developed an all-solid-state multifunctional smart window, in which tungsten oxide (WO3)-based EC and vanadium oxide (VO2)-based TC cells were integrated into a single device. In hybrid smart windows, the WO3-based EC layer modulates optical transm...

To resist the energy crisis and increasingly environmental pollution, there is a great demand for the development of sustainable materials for use in high-performance energy storage devices and environmental applications. However, it is a great challenge to realize both ultrahigh power density and high energy density in symmetric supercapacitors (SCs) by using materials synthesized from bioresources. Herein, we report the synthesis of hierarchical and lightweight graphene aerogels (GAs) with int...

Abstract The direct integration of two-dimensional nanostructures into macroscopic porous carbon substrates is essential for their practical use in potential applications, which is a big challenge due to the difficulty of securing uniform coating layers. In this work, we demonstrate a very simple and effective method for the direct coating of MoS 2 onto the surface of porous carbon structures having nano-sized pores, such as vertically aligned carbon nanotube arrays. A uniform coverage of MoS 2 ...
