**3.7 The gadolinium (Gd3+) and tin (Sn4+) Co-doped BiFeO3 nanoparticles as new solar light active photocatalyst**

The procedure of photocatalysis is engaging tremendous intrigue inspired by the extraordinary guarantee of tending to current vitality and natural issues through changing over sun oriented light straightforwardly into substance vitality. Be that as it may, an effective sun oriented vitality collecting for photocatalysis remains a basic test. Here, we revealed another full sun oriented range driven photocatalyst by co-doping of Gd3+ and Sn4+ into An and B-destinations of BiFeO3 at the same time. The co-doping of Gd3+ and Sn4+ assumed a key job in hampering the recombination of electron-opening sets

and moved the band-hole of BiFeO3 from 2.10eV to 2.03eV. The Brunauer-Emmett-Teller (BET) estimation affirmed that the co-doping of Gd3+ and Sn4+ into BiFeO3 expanded the surface region and porosity, and in this way the photocatalytic movement of the Bi0.90Gd0.10Fe0.95Sn0.05O3 framework was fundamentally improved. The work proposed another photocatalyst that could corrupt different natural colors like Congo red, Methylene blue, and Methyl violet under illumination with various light wavelengths and gave direction for planning progressively productive photocatalysts [21].

*3.9.1 What is gadolinium differentiate medium?*

A Gd(III)-based permeable metal–natural system (MOF), Gd-pDBI, has been blended utilizing fluorescent linker pDBI (pDBI = (1,4-bis(5-carboxy-1H-benzimidazole-2-yl)benzene)), bringing about a three-dimensional interpenetrated structure with an one-dimensional open channel (1.9 × 1.2 nm) loaded up with hydrogen-bonded water gatherings. Gd-pDBI shows high warm steadiness, porosity, amazing water solidness, alongside organic-solvent and mellow corrosive and base soundness with maintenance of crystallinity. Gd-pDBI was changed to the nanoscale system (ca. 140 nm) by mechanical pounding to yield MG-Gd-pDBI with phenomenal water dispersibility (>90 min), keeping up its porosity and crystallinity. In vitro and in vivo investigations on MG-Gd-pDBI uncovered its low blood poisonous quality and most noteworthy medication stacking (12 wt%) of anticancer medication doxorubicin in MOFs answered
