“…3 Generally speaking, the NiFePSe nanocages are endowed with a variety of functionalities, 50 as strikingly illustrated in Fig. 5d: (1) the highly open 3D porous architecture, delicate internal voids, and numerous surface defects contribute to exposing more accessible active sites and shortening the electron/mass transfer pathways; (2) the formation of heterogeneous interfaces within NiFePSe could induce a strong interfacial synergy effect and efficient redistribution of electrons for optimizing the adsorption of reactive species, [51][52][53][54] thereby contributing to the excellent OER performance; (3) the superhydrophilicity of electrocatalysts enables significantly improved mass transport between electrolytes and electrodes as well as benefits the adsorption of H 2 O. Therefore, the heterostructured NiFePSe hollow nanocages are conceivably believed to be a desirable electrocatalyst for an effective OER process.…”

“…The adsorption characteristics of Cu 2+ on AC-12 and AC-12@CD were of unimolecular adsorption with uniform distribution of active groups on the adsorbent surface [ 24 , 29 ]. The functional groups such as –NH x , –OH, and –COOH in the adsorbent could remove metal pollution through electronic interaction with charged metal ions in the solution [ 30 , 31 ].…”

In this paper, Ganoderma lucidum bran was explored as the precursor to fabricate biomass activated carbon. When potassium hydroxide was selected as an activator (1:6, mass ratio of AC-12 to potassium hydroxide), and the activation condition was 700 °C at 5 h, the highest specific surface area reached 3147 m2 g−1. Carbon dots were prepared with citric acid monohydrate and thiourea as precursors and then loaded onto the surface of activated carbon by a simple and green method. Activated carbon for dual-functional had a high adsorption capacity. Additionally, based on its unique optical properties, the fluorescence response for detecting copper ion was established. The fluorescence intensity of the materials decreased linearly with the increase of copper ion concentration, in the range of 10–50 nmol L−1. The research opened up a new way for applying biomass activated carbon in the field of adsorption and detection. Highlights: (1) Carbon dots were loaded on the surface of activated carbon; (2) the simultaneous adsorption and detection were realized; (3) it provides a way for the preparation of dual-functional materials.

“…The maximum value of the adsorption capacity occurred at pH 7, which was 83.4 mg g −1 . Compared with some reported materials (e.g., ZIF–8, ZIF–67, ZIF–8@ZIF–67 [ 39 ]; polyamide grafted carbon microspheres [ 40 ]), the adsorption capacity of the activated carbon delivers a relatively desirable level.…”

Waste-Coffee-Derived Activated Carbon as Efficient Adsorbent for Water Treatment

Activated carbon prepared from waste coffee was utilized as a potential low-cost adsorbent to remove Rhodamine B from aqueous solution. A series of physical characterizations verify that the obtained activated carbon possesses a layered and ordered hexagonal structure with a wrinkled and rough surface. In addition, high specific surface area, appropriate pore distribution, and desired surface functional groups are revealed, which promote the adsorption properties. Various adsorption experiments were conducted to investigate the effect on the absorption capacity (e.g., of initial dye concentration, temperature and solution pH) of the material. The results showed that the waste-coffee-derived activated carbon with a large surface area of approximately 952.7 m2 g−1 showed a maximum uptake capacity of 83.4 mg g−1 at the pH of 7 with the initial dye concentration of 100 mg L−1 under 50°C. The higher adsorption capacity can be attributed to the strong electrostatic attraction between the negatively charged functional groups in activated carbon and the positively charged functional groups in RB. The kinetic data and the corresponding kinetic parameters were simulated to evaluate the mechanism of the adsorption process, which can fit well with the highest R2. The adsorption results confirmed the promising potential of the as-prepared waste-coffee-derived activated carbon as a dye adsorbent.
