•The crytalline 3D MOFs DHTZn was successfully synthesized by hydrothermal method.•The CO2 adsorption uptake values are 462 cm3 g−1 at 273 K and 379 cm3 g−1 at 298 K.•The N2 adsorption uptake values are 230 cm3 g−1 at 273 K and 188 cm3 g−1 at 298 K.•The surface area is found to be 875 cm3 g−1 at 273 K and 792 cm3 g−1 at 298 K.•DHTZn was an excellent probe for Cu2+ ion and sensitive nature was indicated.
This report investigates infinite three-dimensional d-histidine based bio-metal organic framework single crystal (DHTZn) for versatile applications. Sorption analysis at different temperatures indicates DHTZn crystal has excellent adsorption capacity for CO2 (462 cm3 g−1 at 273 K and 379 cm3 g−1 at 298 K) when compared to N2 (230 cm3 g−1 at 273 K and 188 cm3 g−1 at 298 K). The DHTZn was effectively sensing Cu2+ ions, KSV value and detection limits are 4.24 × 105 M−1 and 0.0947 × 10−7 M respectively. Based on the above outcomes, DHTZn crystal might be useful for selective sorption and separation of CO2 with Cu2+ ion sensing.
