“…Silylation alters the microstructure by switching it from regular porous cells to a random tridimensional assembly of thin sheets [ 83 ]. The samples without hydrophobic modification exhibit WCA between 132–145° [ 80 , 81 , 84 , 85 , 86 , 87 ]. The surface silylation could be achieved using methyltrimethoxysilane (MTMS) [ 9 , 24 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 ] (WCA 130–152°), trimethylchlorosilane (TMCS) [ 82 ] (WCA 137–146°), hexadecyltrimethoxysilane (HDTMS) in a combination of MTMS [ 78 ] (WCA 107–159), or silicon ceramic coating powder (SCCP) [ 92 ].…”

The increment in water pollution due to the massive development in the industrial sector is a worldwide concern due to its impact on the environment and human health. Therefore, the development of new and sustainable alternatives for water remediation is needed. In this context, aerogels present high porosity, low density, and a remarkable adsorption capacity, making them candidates for remediation applications demonstrating high efficiency in removing pollutants from the air, soil, and water. Specifically, polymer-based aerogels could be modified in their high surface area to integrate functional groups, decrease their hydrophilicity, or increase their lipophilicity, among other variations, expanding and enhancing their efficiency as adsorbents for the removal of various pollutants in water. The aerogels based on natural polymers such as cellulose, chitosan, or alginate processed by different techniques presented high adsorption capacities, efficacy in oil/water separation and dye removal, and excellent recyclability after several cycles. Although there are different reviews based on aerogels, this work gives an overview of just the natural biopolymers employed to elaborate aerogels as an eco-friendly and renewable alternative. In addition, here we show the synthesis methods and applications in water cleaning from pollutants such as dyes, oil, and pharmaceuticals, providing novel information for the future development of biopolymeric-based aerogel.

“…They can be made into aerogel, silica nanoparticles, adsorbents, and composites. Adding BLF into NRL foam should positively affect the environment, society, and the economy [ 42 ]. However, limited information is available regarding how the BLF affects the cushion performance of NRL foam, especially for fresh produce packaging applications.…”

Bamboo leaf fiber (BLF) was incorporated into an eco-friendly foam cushion made from natural rubber latex (NRL) to enhance the biodegradation rate. The objective of this work was to investigate the effects of BLF content on the foam structure, mechanical properties, cushion performance, and biodegradability. The NRL foam cushion nets with and without BLF were prepared using the Dunlop method along with microwave-assisted vulcanization. BLF (90–106 µm in length) at various loadings (0.00, 2.50, 5.00, 7.50, and 10.00 phr) were introduced to the latex compounds before gelling and vulcanizing steps. Scanning electron microscopy (SEM) showed that the BLF in a NRL foam caused an increase in cell size and a decrease in the number of cells. The changes in the cell structure and number of cells resulted in increases in the bulk density, hardness, compression set, compressive strength, and cushion coefficient. A soil burial test of 24 weeks revealed faster weight loss of 1.8 times when the BLF content was 10.00 phr as compared to the NRL foam without BLF. The findings of this work suggest the possibility of developing an eco-friendly cushion with a faster degradation rate while maintaining cushion performance, which could be a better alternative for sustainable packaging in the future.

“…Tourmaline has permanent spontaneous polarization, thermoelectricity, infrared radiation, and good adsorption properties, which contribute to the adsorption of organic matter or promote the formation of hydroxyl radicals and reduce the high electron-hole recombination rate, making it an environmentally friendly material [8]. However, the preparation of g-C 3 N 4 /BiOI containing tourmaline has rarely been reported so far.…”

In this study, g-C3N4/BiOI/tourmaline composites were synthesized by loading BiOI and tourmaline on g-C3N4 nanofilms using g-C3N4, BiOI, and tourmaline as raw materials, aiming to optimize the photocatalytic degradation of amaranth red dye wastewater (AR). Single-factor experiments were conducted to optimize the degradation process. The findings indicate that a degradation rate of 95.88% can be achieved for AR within 150 min of light exposure, given a g-C3N4/BiOI/tourmaline dosage of 1 g/L, an initial pH level of 3 for the AR, and an initial AR concentration of 10 mg/L. Upon repeating the experiment for five cycles, the composite exhibited 83.10% activity, demonstrating its stability. Various analytical techniques were employed for material characterization: X-ray diffractometry (XRD) to ascertain the crystalline structure, field-emission scanning electron microscopy (FESEM) to evaluate morphology, X-ray photoelectron spectroscopy (XPS) for elemental analysis, ultraviolet–visible diffuse reflectance spectroscopy (UV-vis DRS) for optical properties, and photoluminescence (PL) spectroscopy to analyze the recombination of excited electrons and holes. Free radical masking experiments further elucidated the photocatalytic mechanism, revealing that the primary active species in the degradation process is the superoxide anion (O2−). This research offers a novel approach to address the limitations of n-type metal-free semiconductor photocatalysts.
