“…To the best of our knowledge, this is the rst report on the fast reduction of organic water pollutants using copper metal immobilized on HAP as a solid catalyst in the presence of NaBH 4 . In this investigation, HAP was produced from ES biowaste using a straightforward, ecologically responsible hydrothermal process [30]. Following copper sulfate surface coating was employed as an e cient, heterogeneous catalyst to break down certain OPDs in aqueous media at ambient temperature.…”

Conversion of biowastes into valuable products will assist sustainable development and waste management. Eggshell could be used as a bio-template for the synthesis of hydroxyapatite and widely applied in the field of catalytic processes. In this study, copper sulfate supported on hydroxyapatite (CuSO4@HAP) was rationally fabricated using biowaste eggshells (ES) by hydrothermal method and it was used for the fast catalytic degradation of organic pollutant dyes (OPDs) such as methylene blue (MB), 4-nitrophenol (4-NP) and 4-nitroaniline (4-NA) in the presence of sodium borohydride (NaBH4) in aqueous media. The physical and chemical properties of CuSO4@HAP were characterized via FTIR, XRD, BET, TEM, FE-SEM/EDS, and elemental mapping analyses. Results indicated that the synthesized catalyst was crystalline with great purity, homogeneous with fine particles, and mesoporous with a high specific surface area. Besides, the reaction progress was evaluated using a double-beam UV-vis spectrophotometer. The reaction conversion (%) under optimal conditions rapidly increased to an equilibrium state (99% for 4-NP, 96% for 4-NA, and 99.5% for MB) within a short time (t < 10 min). In addition, the catalytic rate constant of MB, 4-NP, and 4-NA in the presence of NaBH4 and CuSO4@HAP was calculated to be about 0.514, 0.492, and 0.317 min− 1, respectively. This study demonstrates the potential use of natural HAP-derived catalyst from biowaste eggshell with high efficiency and stability for degrading OPDs under mild reaction conditions. Additionally, CuSO4@HAP could be effectively separated and reused for four cycles with almost the same catalytic efficacy.

“… 19 Currently, EPA has ranked eggshells at 15 th as one of the environmental problem makers, and more than 100 000 dollars has been paid for the landfill disposal of eggshells in the USA every year. 20 Due to being rich in calcium carbonate and a natural porous structure, eggshells have a potential application to adsorb heavy metals, 21 organic dyes, 22 and anions. 23 As a calcium-based material, eggshells own high fluoride affinity and biocompatibility.…”

“…Existe la posibilidad de sintetizar hidroxiapatita a partir de una fuente natural, de un desecho como la cáscara de huevo de gallina (14)(15)(16)(17)(18)(19)teniendo en cuenta su composición rica en Calcio [20], sin embargo, aunque hay numerosos estudios en los que se ha obtenido Ha-h, hay pocos estudios documentados que hablan de la bioactividad de dicho material [21], se tienen preguntas en cuanto al comportamiento de este material en un ambiente fisiológico, de su grado de biocompatibilidad y bioactividad necesarias para aplicaciones biomédicas [22][23][24], en este caso, necesarias para determinar si es viable o no usar este material como aditivo para cementos óseos. Por lo tanto, en este trabajo se tuvo como objetivo evaluar el carácter bioactivo de muestras de HA-h para posible aplicación como cemento óseo.…”

Los biomateriales se han constituido como una herramienta fundamental en la ingeniería de tejidos y la medicina regenerativa, debido a que tratan y en algunos casos logran mimetizar el tejido original. Actualmente se estudian los cementos óseos como biomateriales sustitutos de hueso en diferentes patologías, y se analizan diferentes compuestos con contenido de hidroxiapatita para dotarlos de bioactividad. En el presente estudio se tuvo como objetivo evaluar el carácter bioactivo en muestras de hidroxiapatita obtenida a partir de cáscara de huevo para usarse como posible adición a los cementos óseos. La síntesis de la hidroxiapatita se realizó por el método de precipitación, en la que se usó el óxido de calcio proveniente de las cáscaras de huevo y el ácido fosfórico como fuentes de calcio y fósforo, respectivamente. La caracterización química realizada por medio de espectroscopia Raman y EDS, permitió evidenciar que se logró obtener hidroxiapatita a partir de éste residuo con una relación Ca/P de 2,187. Para el estudio de bioactividad, se sumergieron las muestras en polvo en un fluido biológico simulado durante 14 y 28 días, y con espectroscopia Raman y microscopía SEM-EDS, se caracterizaron las muestras tanto antes como después del tratamiento para determinar su relación Ca/P y comportamiento con el tiempo. Las técnicas de caracterización permitieron determinar que la hidroxiapatita de cáscara de huevo presenta propiedades bioactivas y que además es un material estable al estar en contacto con el fluido biológico simulado, una gran candidata para usarse como adición a los cementos óseos convencionales.
