Heterogeneous catalysis is one of the fastest developing branches of chemistry. Moreover, it is strongly connected to popular environment-related applications. Owing to the very fast changes in this field, for example, numerous discoveries in nanoscience and nanotechnologies, it is believed that an update of the literature on heterogeneous catalysis could be beneficial. This review not only covers the new developments of heterogeneous catalysis in environmental sciences but also touches its historical aspects. A short introduction to the mechanism of heterogeneous catalysis with a small section on advances in this field has also been elaborated. In the first part, recent innovations in the field of catalytic air, water, wastewater and soil treatment are presented, whereas in the second part, innovations in the use of heterogeneous catalysis for obtaining sustainable energy and chemicals are discussed. Catalytic processes are ubiquitous in all branches of chemistry and there are still many unsolved issues concerning them.

“…[10] Transition metal nanoparticles are an emerging topic with relevant applications in organic synthesis, especially as heterogeneous catalysts in several chemical transformations. [11][12][13][14] Nanoparticles are remarkably interesting due to their intrinsic properties characterized by very small size and an extremely large surface-to-volume ratio, which translates into unique optical, physical, and chemical properties. Recently, metal nanoparticles (AgNPs, BF 3 -grafted Fe 3 O 4 @SucroseNPs or P4VPy-CuONPs) have been used in the synthesis of bis(indolyl)methanes from ketones, aldehydes or directly from alcohols (Scheme 2).…”

Palladium nanohybrids were synthesized and applied to the one‐pot synthesis of bis(3‐indolyl)methanes by selective C−C bond reaction from benzyl alcohol and indole. A T. lanuginosus lipase‐palladium nanoparticles hybrid (Pd@TLL) was synthesized, yielding PdNPs with an average diameter size of 5 nm. This heterogeneous catalyst was first tested in the selective oxidation of benzyl alcohol to benzaldehyde in different solvents. Then, the direct formation of bis(3‐indolyl)methane, by in situ oxidation and C−C coupling, was successfully evaluated under different conditions, obtaining >99 % conversion at 80 °C in toluene, with a TOF value of 9 min−1 and 89 % in pure water, demonstrating the versatility of these biohybrids.

Biosorptive removal of divalent nickel from aqueous solution using Carissa Carandas and Syzygium aromaticum was investigated in batch mode and the observations were correlated with the pH variation, agitation time, dose of the adsorbent and initial metal ion concentration in the solution. In the course of this study Sorption efficiency of C. carandas leaf powder found higher than that of S. aromaticum under identical experimental conditions. The maximum adsorption capacities estimated for Ni(II) through Freundlich isotherm model were 3.76 and 2.96 mg/g for C. carandas and S. aromaticum, respectively. In kinetic studies the correlation coefficient (R 2 = 0.99) for the pseudo-second order kinetics modal was higher than that of pseudo-first order kinetics model and the calculated value of q e for the pseudo-second order kinetic model resulted very close to the experimental value, which indicates that it fits well with the equilibrium data for Ni(II) sorption from aqueous solutions on biosorbents.
