“…The energy consumption was 0.44 kWh dm −3 and 0.29 kWh dm −3 for PH removal in the cases of Cu-PA and Cu-PA-IL, respectively, based on Equation (1). Also, computational approaches are systematically used in environmental science to assist the experiment in order to expedite and save resources and costs [45,46].…”

Coordination polymer (CP)-type adsorbents impregnated with ionic liquids that are used to remove phenol from wastewater must be regenerated. A simple washing of the adsorbent releases about 70% from the spent adsorbent. In order to increase and study the phenol release, an electrochemical method was used. For this purpose, an electrochemical commercial graphite electrode was used as the working electrode, and the electrolyte support was a 3% NaCl solution. During the electrochemical investigation, the spent CP was immersed in a saline solution. The PH content in the electrolyte affected the direct electrooxidation (EO); the formation of BQ appeared to be accelerated by a lower concentration and a slower release of PH. After 90 min, an efficiency of PH electrooxidation (EOPH) of 36.22% from Cu-PA and EOPH of 42.14% from Cu-PA-IL, respectively, was achieved. These results were significantly higher than the EOPH of the solution resulting from washing the wasted adsorbent with a saline solution (22.58%). This work highlights the potential for the simultaneous electrooxidation of desorbed PH and the recovery of spent adsorbent in this situation. The number of cycles in which the adsorbent can be used without losing its absorbance ability is three.

“…40 Compared to sulfur, relatively few examples of oxygen–gold bonds are known in the inorganic synthetic literature, though recently phenols were found to bind to Au surfaces to form self-assembled monolayer with similar properties to thiols. 41 The few examples of oxygen–metal (O–M) binding in single molecule junction studies typically involve two binding moieties to form bidentate links such as with amides or with carboxyl groups to strengthen the metal–molecule interaction. 37,39,42–45 The specific monodentate O–M binding with a hydroxy group such as alcohol, phenol or ether group have not been observed in a molecular junction for conductance measurements on gold.…”
